At this time, it is preferable to wear the diaper in such a manner that it does not protrude from under the underpants. However, since a general diaper is composed of a sheet member having high flexibility such as non-woven fabric, in the operation of pulling up the diaper or the operation of adjusting the position, the sheet member is likely to be stretched when stretched, and the stretched portion is present. Prominent from the underwear. In particular, in order to bond the absorbent body, when the upper end portions of the abdominal side and the back side of the absorbent body are respectively stretched upward, the upper end portion is stretched, and a part of the absorbent body is easily protruded from the upper end of the underwear. Further, if the size of each portion of the diaper is larger than the size of the undergarment, the diaper is not easily stored under the undergarment. The present invention has been made in view of the conventional problems as described above, and an object thereof is to provide a pants-type diaper which is less likely to protrude beyond the undergarment when it is worn under the undergarment. (Means for Solving the Problem) [0006] The main invention for achieving the above object is a pants-type diaper having a waist-shaped opening portion and a pair of leg-opening portions, which are formed in a longitudinal direction and a lateral direction, which intersect each other, and which have a waist-shaped opening portion and a pair of leg-opening portions. The absorbent body includes an absorbent body that absorbs excretion liquid, a skin-side non-woven fabric that is disposed on the skin side closer to the skin than the absorbent body, and is disposed closer to the skin than the absorbent body. a liquid-impermeable non-skin side film on the side and an outer nonwoven fabric disposed closer to the non-skin side than the non-skin side film; and a belt portion disposed on each of the lateral sides to absorb the absorbent The end portions of the main body in the longitudinal direction are coupled to each other, and the belt portion is a pair of joint portions that are inclined toward the lower side of the longitudinal direction and the lateral outer side by the waist opening portion toward the leg-opening portion, and the absorption portion The main body is joined, and the minimum value of the distance between the end of one side of the belt portion and the end of the other side in the longitudinal direction is 50 mm or more and 100 mm or less. In the longitudinal direction, the region of the absorbent body that is closer to the upper side than the upper end of the non-skin side film has at least three layers including the skin side nonwoven fabric layer and the outer nonwoven fabric layer, and the joint portion is non-woven. The skin side is erected, and the end portion of the non-skin side has a dry edge in which the absorbent body and the belt portion are not joined, and the dry side of the both end portions in the longitudinal direction of the joint portion The width is shorter than the width of the dry side in the central portion in the longitudinal direction of the joint portion, and the width of the dry side in the central portion in the longitudinal direction of the joint portion is larger than the width of the joint portion. Shorter. Other features of the present invention will be apparent from the description and appended claims. (Effects of the Invention) According to the present invention, it is possible to provide a pants-type diaper which is less likely to protrude beyond the undergarment when it is worn under the undergarment.
[0009] 藉由本說明書及所附圖示之記載,至少以下事項清楚可知。 [0010] 一種短褲型紙尿褲,其係具有彼此交叉的縱向與橫向,形成有腰圍開口部與一對腿圍開口部的短褲型紙尿褲,其特徵為:具有:吸收性本體,其係具備有:吸收***液的吸收體、配置在比前述吸收體更靠近肌膚側的液透過性的肌膚側不織布、配置在比前述吸收體更靠近非肌膚側的液不透過性的非肌膚側薄膜、及配置在比前述非肌膚側薄膜更靠近非肌膚側的外裝不織布;及帶部,其係分別配置在前述橫向的兩側,將前述吸收性本體的長邊方向的各端部相連結,前述帶部係以由前述腰圍開口部朝向前述腿圍開口部而朝前述縱向的下側而且前述橫向的外側傾斜的二對接合部,與前述吸收性本體相接合,前述縱向中的前述帶部的一方側之端與另一方側之端之間的距離的最小值係50mm以上100mm以下,在前述縱向,前述吸收性本體之中比前述非肌膚側薄膜的上端更靠近上側的區域係具有包含前述肌膚側不織布之層及前述外裝不織布之層的至少3層。 [0011] 藉由如上所示之短褲型紙尿褲,與內褲重疊穿用時,容易連同內褲一起將帶部朝斜上方拉伸向上而使貼合性容易提升。此外,帶部的寬度被限制在預定範圍內,因此帶部容易抓住,穿用後,帶部不易從內褲的側邊部分突出。此外,吸收性本體的上端部為3層構造,因此該部分的強度變高,當將吸收性本體上拉時,該部分不易伸展。因此,與內褲重疊穿用時,吸收性本體的上端部不易從內褲突出,此外,將吸收體牢牢地上拉,藉此可實現良好的貼合性。 [0012] 在該短褲型紙尿褲中,較佳為具有被配置在比前述肌膚側不織布更靠近肌膚側的液不透過性的疏水性薄片。 [0013] 藉由如上所示之短褲型紙尿褲,在吸收性本體的縱向端部的肌膚側面設置疏水性薄片,藉此抑制吸收性本體所吸收的***液返回至肌膚側而滲出的情形,可不易給穿用者帶來不舒服感。此外,在吸收性本體的縱向端部區域,因與肌膚側不織布或外裝不織布積層,可提高該區域的強度。 [0014] 在該短褲型紙尿褲中,較佳為將前述吸收性本體之中比前述非肌膚側薄膜的上端更靠近上側的區域以50N的力朝前述縱向的上側拉伸時的伸展量為1.0mm以下。 [0015] 藉由如上所示之短褲型紙尿褲,穿用紙尿褲時,即使在吸收性本體之中比非肌膚側薄膜的上端更靠近上側的區域朝上方被拉伸的情形下,該區域亦不易伸展,抑制吸收性本體的上端部由內褲突出。此外,藉由拉伸該區域,可將吸收體牢牢地上拉,因此可實現良好的貼合性。 [0016] 在該短褲型紙尿褲中,較佳為前述吸收性本體之中比前述非肌膚側薄膜的上端更靠近上側的區域的前述縱向中的長度為20mm以上。 [0017] 藉由如上所示之短褲型紙尿褲,吸收性本體之中比非肌膚側薄膜的上端更靠近上側的區域係在穿用紙尿褲時穿用者拉伸吸收性本體時容易用手指抓住的區域,因此藉由形成為一邊充分確保該區域之強度一邊容易抓住的大小的區域,穿用者可輕易進行上拉吸收性本體的動作。 [0018] 在該短褲型紙尿褲中,較佳為前述帶部係具有上端部以前述縱向折返的端部終尾構造,前述吸收性本體之中比前述非肌膚側薄膜的上端更靠近上側的區域的前述縱向中的長度係比前述帶部之中具有前述端部終尾構造的部分的前述縱向中的長度為更短。 [0019] 藉由如上所示之短褲型紙尿褲,帶部的上側端部區域被拉伸至吸收性本體之中比非肌膚側薄膜的上端更靠近上側的區域,而容易一起被上拉至上方。因此,藉由上拉吸收性本體的動作,容易調整包含帶部的腰圍開口部的全體的位置(高度),貼合性提升,並且紙尿褲不易從內褲突出。 [0020] 在該短褲型紙尿褲中,較佳為在前述吸收性本體的腹側,在前述縱向比前述非肌膚側薄膜的上端更靠近上側的區域所形成的皺褶的高度的最大值係比在前述吸收性本體的背側,在前述縱向比前述非肌膚側薄膜的上端更靠近上側的區域所形成的皺褶的高度的最大值為更小。 [0021] 藉由如上所示之短褲型紙尿褲,當將紙尿褲重疊穿用在內褲之下時,抑制在腹側,內褲被過度上舉至厚度方向的非肌膚側而紙尿褲在內褲之下混亂的情形,容易獲得良好的貼合性。此外,將紙尿褲穿用在內褲之下較不易顯眼。 [0022] 在該短褲型紙尿褲中,較佳為在前述吸收性本體的腹側及背側中,在前述縱向的上端而且前述橫向的中央,係具有朝前述縱向的上側突出的前端突出部。 [0023] 藉由如上所示之短褲型紙尿褲,使用者係一看就容易辨識紙尿褲的橫向的中央位置。藉此,穿用紙尿褲時,可易於使吸收性本體貼合在身體正確位置,可有效抑制因吸收性本體在橫向偏離的狀態下被穿用所致之***物橫漏等。 [0024] 在該短褲型紙尿褲中,較佳為前述前端突出部以在前述縱向比前述接合部的上端更靠近上側突出的長度為1mm以上、5mm以下。 [0025] 藉由如上所示之短褲型紙尿褲,因將前端突出部的突出長度形成為1mm以上,抑制前端突出部變得難以視認的情形。接著,藉由將前端突出部的突出長度形成為5mm以下,抑制前端突出部捲曲或折曲、或從內褲突出的情形。藉此,前端突出部容易發揮作為表示橫向的中央位置的記號的功能。 [0026] 在該短褲型紙尿褲中,較佳為前述帶部係具有沿著前述帶部的長邊方向作伸縮的複數彈性構件,前述彈性構件係由前述帶部的長邊方向的一端至另一端連續配置。 [0027] 藉由如上所示之短褲型紙尿褲,因彈性構件針對長邊方向不具有非連續部,不會有將帶部朝斜上方向拉伸之力在途中分斷的情形而作用在彈性構件,遍及帶部的長邊方向的全長,展現伸縮性。藉此,上拉吸收性本體的效果提升,可更加提高紙尿褲的貼合性。 [0028] 在該短褲型紙尿褲中,較佳為前述接合部係以在非肌膚側豎立的方式而設,在前述非肌膚側的端緣部係具有前述吸收性本體與前述帶部未相接合的乾邊,前述接合部的長邊方向的兩端部中的前述乾邊的寬度係比前述接合部的長邊方向的中央部中的前述乾邊的寬度為更短。 [0029] 藉由如上所示之短褲型紙尿褲,在腰圍開口部或腿圍開口部附近縮小乾邊的寬度,藉此抑制內褲與接合部相干擾,在穿用紙尿褲時,可使穿用者不易產生腰圍或腿圍的違和感。 [0030] 在該短褲型紙尿褲中,較佳為在自然狀態下,前述帶部的前述橫向的外側端而且前述縱向的上側端的位置係比前述吸收性本體的上側端更靠近前述縱向的上側。 [0031] 藉由如上所示之短褲型紙尿褲,帶部從自然狀態而朝向斜上,因此當將帶部抓住而上拉時,力容易以斜向施加,力容易傳至吸收性本體的全域。藉此,帶部容易以斜上方上拉,吸收性本體亦容易與該帶部連動一邊被上拉一邊擴幅。因此,容易使紙尿褲的貼合性提升。 [0032] 在該短褲型紙尿褲中,較佳為在自然狀態下,前述帶部的前述橫向的外側端而且前述縱向的下側端的位置係比前述帶部的前述橫向的外側端而且前述縱向的上側端的位置更靠近前述橫向的外側。 [0033] 藉由如上所示之短褲型紙尿褲,以手抓住的部分亦即帶部的橫向兩端部形成斜向,因此容易進行抓住帶部而上拉的動作。 [0034] 此外,可知一種短褲型紙尿褲,其係具有彼此交叉的縱向與橫向,形成有腰圍開口部與一對腿圍開口部,且被穿用在內褲之下的短褲型紙尿褲,其特徵為:具有:吸收性本體,其係具備有:吸收***液的吸收體、配置在比前述吸收體更靠近肌膚側的液透過性的肌膚側不織布、配置在比前述吸收體更靠近非肌膚側的液不透過性的非肌膚側薄膜、及配置在比前述非肌膚側薄膜更靠近非肌膚側的外裝不織布;及帶部,其係分別配置在前述橫向的兩側,將前述吸收性本體的長邊方向的各端部相連結,前述帶部係以由前述腰圍開口部朝向前述腿圍開口部而朝前述縱向的下側而且前述橫向的外側傾斜的二對接合部,與前述吸收性本體相接合,前述縱向中的前述帶部的一方側之端與另一方側之端之間的距離的最小值係50mm以上100mm以下,前述帶部、及前述吸收性本體的***部係被調整為穿用前述內褲之後隱藏在前述內褲的位置的大小。 [0035] 藉由如上所示之短褲型紙尿褲,在紙尿褲重疊穿用內褲,藉此不易產生穿用紙尿褲時的違和感,穿用者可以穿用一般內褲的感覺過著日常生活。此時,紙尿褲隱藏在內褲之下而不易顯眼,因此穿用者不易意識到正在穿用紙尿褲,不易產生精神上的不安感。 [0036] 此外,可知一種短褲型紙尿褲的穿用方法,該短褲型紙尿褲係具有彼此交叉的縱向與橫向,形成有腰圍開口部與一對腿圍開口部,具備有:吸收性本體,其係具備有:吸收***液的吸收體、配置在比前述吸收體更靠近肌膚側的液透過性的肌膚側不織布、配置在比前述吸收體更靠近非肌膚側的液不透過性的非肌膚側薄膜、及配置在比前述非肌膚側薄膜更靠近非肌膚側的外裝不織布;及帶部,其係分別配置在前述橫向的兩側,將前述吸收性本體的長邊方向的各端部相連結,以由前述腰圍開口部朝向前述腿圍開口部而朝前述縱向的下側而且前述橫向的外側傾斜的二對接合部,與前述吸收性本體相接合,該短褲型紙尿褲的穿用方法係具有:在內褲的肌膚側重疊配置前述短褲型紙尿褲;在前述短褲型紙尿褲及前述內褲的腿圍開口部穿過穿用者的腳之後,連同前述內褲的側邊部分一起將前述帶部以斜上方上拉;及在腹側及背側中,連同前述內褲的前述縱向的上端部一起將前述吸收性本體的前述縱向的上端部以上方上拉。 [0037] 藉由如上所示之短褲型紙尿褲的穿用方法,在紙尿褲重疊穿用內褲,藉此不易產生穿用紙尿褲時的違和感,穿用者可以穿用一般內褲的感覺過著日常生活。接著,藉由一起穿用內褲與紙尿褲,相對內褲,紙尿褲的位置不易偏離,此外,可以不會從內褲之下突出的方式穿用紙尿褲。 [0038] ===實施形態=== 說明作為本實施形態之吸收性物品之一例的短褲型用後即棄紙尿褲1(以下亦稱為紙尿褲1)。本實施形態之紙尿褲1係可重疊穿用在內褲之下,此時,以可不會從內褲突出地穿用的方式構成各部。圖1係紙尿褲1的概略斜視圖。該紙尿褲1係在穿用前的時點已經形成為如圖1所示之短褲型狀態。接著,在該短褲型狀態下,同紙尿褲1係具有彼此正交的縱向與橫向與前後方向。其中,穿用同紙尿褲1時,上述縱向大多朝向上下方向。因此,以下將縱向亦稱為「上下方向」。此外,關於該上下方向,上側對應穿用者的腰圍側,下側對應穿用者的***側。另一方面,關於前後方向,前側對應穿用者的腹側,後側對應穿用者的背側。 [0039] 此外,在同短褲型狀態下,紙尿褲1係具有:一邊以上下方向沿著長邊方向,一邊在同長邊方向的大致中央位置CLL10(圖2A)對折的帶狀的吸收性本體10;分別配設在橫向的兩側,將上述吸收性本體10中的長邊方向的各端部10eLf、10eLb彼此相連結的各帶部32、32;及分別位於吸收性本體10的橫向的兩側而形成腿圍開口部LH的各腿摺邊部37、37。 [0040] 亦即,吸收性本體10的各端部10eLf、10eLb之中的一方端部10eLf係位於上方且前側,另一方的端部10eLb係位於上方且後側。此外,在紙尿褲1的前側,由縱向的上側朝下側、而且由橫向的內側朝外側呈傾斜的前側接合部jf、jf(相當於接合部)以橫向排列設有一對,同樣地,在紙尿褲1的後側,亦由縱向的上側朝下側、而且由橫向的內側朝外側呈傾斜的後側接合部jb、jb(相當於接合部)以橫向排列設有一對。接著,藉由前者的一對前側接合部jf、jf,位於前側的吸收性本體10的端部10eLf與各帶部32、32的橫向的端部32eLf、32eLf相接合,並且位於前側的各腿摺邊部37、37的端部37eLf、37eLf與各帶部32、32的橫向的端部32eLf、32eLf相接合。此外,同樣地,藉由後者的一對後側接合部jb、jb,位於後側的吸收性本體10的端部10eLb與各帶部32、32的橫向的端部32eLb、32eLb相接合,並且位於後側的各腿摺邊部37、37的端部37eLb、37eLb與各帶部32的橫向的端部32eLb、32eLb相接合。 [0041] 接著,藉此,在同短褲型狀態中,藉由吸收性本體10的上述各端部10eLf、10eLb與各帶部32、32的上端部,在紙尿褲1的上部形成有腰圍開口部BH。此外,藉由各腿摺邊部37、37中的橫向的外側的端部與各帶部32、32的下端部,在橫向的兩側形成有一對腿圍開口部LH、LH。 [0042] 此外,在各帶部32係分別以上下方向排列複數沿著橫向的絲線橡膠33、33…來作配置,藉此,在各帶部32被賦予橫向伸縮性。另一方面,在各腿摺邊部37亦分別以橫向排列複數沿著吸收性本體10的長邊方向的絲線橡膠38、38來作配置,藉此,各腿摺邊部37被賦予上下方向的伸縮性。接著,根據該等的伸縮性,紙尿褲1的腰圍開口部BH及腿圍開口部LH係分別貼合在穿用者的腰圍或腿圍。 [0043] 此外,如圖3所示,帶部32係形成腰圍開口部BH的部分(圖3中為帶部32的橫向外側端部)筆直地延伸,相對於此,形成腿圍開口部LH的部分(圖3中為帶部32的橫向內側端部)係描出凸向腰圍開口部BH側的曲線(R形狀)。藉此,在形成為短褲型的狀態下,腿圍開口部LH變得容易沿著內褲腿圍的弧形,即使在穿用在內褲之下的情形下,紙尿褲1亦不易從內褲突出。此外,藉由如上所示之曲線形狀,以紙尿褲1的穿用動作(穿用動作的詳細內容將於後述),當將帶部32朝斜上方上拉時,斜上方的力容易作用在短褲型形狀中的帶部32的橫向端部區域,可將帶部32以斜上方順利地上拉。 [0044] 如上所示之紙尿褲1係在其製造過程的最終階段,形成為如圖2A及圖2B所示之延展平板狀態。其中,圖2A係由帶部32側觀看該延展平板狀態的紙尿褲1的概略平面圖,圖2B係圖2A中的B-B剖面圖。在圖3A係在圖2A的延展平板狀態的紙尿褲1中,分別解開前側接合部jf、jf及後側接合部jb、jb的各接合而以看得到吸收性本體10的肌膚側面的方式將各帶部32、32朝橫向的外側打開的狀態的概略平面圖,圖3B係圖3A中的B-B剖面圖。圖4係說明圖3A的C-C剖面的構造的概略剖面圖。此外,圖2B、圖3B及圖4中所示波形線係以模式顯示接著劑者,另外以左斜下線的影線模樣所示部分係以模式顯示熔接部者。 [0045] 圖2A的延展平板狀態的紙尿褲1係相當於在圖1的短褲型狀態的紙尿褲1中以解除吸收性本體10的對折的方式,將同吸收性本體10以與其長邊方向呈平行的前後方向的兩側拉伸而伸展的狀態。接著,在該延展平板狀態下,如圖2B所示,在吸收性本體10及腿摺邊部37、37的各肌膚側面係形成為各帶部32、32相重疊的狀態。 順帶一提,反過來說,若一邊將該延展平板狀態的紙尿褲1中的一對帶部32、32的橫向的內側的各端部32eW1、32eW1分別朝橫向的外側拉伸,一邊將吸收性本體10在長邊方向的大致中央位置CLL10對折,紙尿褲1即成為如圖1所示之短褲型狀態。 [0046] 此外,在該延展平板狀態下,紙尿褲1係具有彼此正交的長邊方向與橫向與厚度方向。接著,該長邊方向係與短褲型狀態的縱向呈平行。此外,同長邊方向的一方側及另一方側係分別對應穿用者的腹側亦即前側及背側亦即後側,因此以下將一方側及另一方側,亦分別稱為「前側」及「後側」。此外,在該延展平板狀態下,同紙尿褲1的長邊方向係吸收性本體10、帶部32、及腿摺邊部37的各長邊方向均對齊。因此,以下將該等未作區別而僅稱為「長邊方向」。另一方面,關於橫向,係與短褲型狀態的橫向相同,以下僅稱為「橫向」。此外,關於厚度方向,將接觸穿用者身體之側亦稱為「肌膚側」,將其相反側亦稱為「非肌膚側」。 [0047] 此外,在該延展平板狀態下,將紙尿褲1形成為以長邊方向伸長的狀態,但是該所謂「伸長的狀態」係指若抵抗因配置在紙尿褲1的各彈性構件(例如帶部32的絲線橡膠33或腿摺邊部37的絲線橡膠38等)所致之收縮力而將紙尿褲1以長邊方向伸長時,伸長至在配置有各彈性構件的部分實質上變得無法視認皺褶或摺邊的程度的狀態。因此,以長邊方向伸長的狀態下的紙尿褲1的形狀係與在藉由各彈性構件所致之收縮力未展現出的狀態下平坦延伸的紙尿褲1的形狀相同。 [0048] 以下一邊適當參照該延展平板狀態的紙尿褲1,一邊說明同紙尿褲1的構成。 在圖2A及圖2B的延展平板狀態下,腿摺邊部37、37分別位於吸收性本體10的橫向的兩側,此外,以重疊在吸收性本體10的肌膚側面及各腿摺邊部37、37的肌膚側面的方式,一對帶部32、32以橫向排列位置。 [0049] 該帶部32及腿摺邊部37係由同一薄片構件30所形成。亦即,如圖3A及圖3B所示,在吸收性本體10的橫向的兩側係分別各1個地配置薄片構件30、30,各薄片構件30、30的橫向的內側的端部30eW、30eW係分別接合在吸收性本體10的橫向的各端部10eW、10eW。詳言之,該內側的端部30eW一邊被介插在構成吸收性本體10之後述之頂面薄片12與背面薄片14或外裝薄片16之間,一邊以接著劑或熔接被接合在該等薄片12、14、16。此外,如圖3B所示,在薄片構件30之中成為帶部32的部分與成為腿摺邊部37的部分之間係設定有沿著長邊方向的折返線FL。接著,在各薄片構件30係分別以橫向跨越該折返線FL的方式以厚度方向貫穿形成有腿圍開口部LH。因此,以該折返線FL將薄片構件30朝橫向的內側折返,藉此形成上述帶部32與腿摺邊部37。接著,以圖2A所示之前述前側接合部jf、jf及後側接合部jb、jb,將吸收性本體10及腿摺邊部37、37與各帶部32、32接合而固定成上述之折返狀態,藉此形成上述延展平板狀態的紙尿褲1。 [0050] 其中,前側接合部jf及後側接合部jb的形成係以例如藉由加熱密封或超音波密封等所為之熔接處理或藉由接著劑所為之接著處理來進行,在此係以熔接處理來進行。 [0051] 此外,如圖3B所示,該薄片構件30的形成係將例如不織布等柔軟薄片30a、30a以厚度方向形成為二塊重疊來進行,接著,在該等二塊重疊的薄片30a、30a彼此之間,前述絲線橡膠33、38,亦即,帶部32的絲線橡膠33、33…及腿摺邊部37的絲線橡膠38、38在以長邊方向伸長的狀態下予以固定。 [0052] 此外,在該例中,如圖2B所示,在帶部32中成為腰圍開口部BH的部分,賦予端部終尾構造,供肌膚壓力減輕用。亦即,在該延展平板狀態的紙尿褲1中,帶部32中的橫向的內側的端部32eW1、32eW1為成為腰圍開口部BH的部分,但是該端部32eW1、32eW1係在橫向折返複數次而以接著劑等固定在該折返狀態,藉此,達成對穿用者的肌膚的負荷減輕。此外,因具有如上所示之端部終尾構造,比帶部32的橫向中央部更靠近橫向的端部(腰圍開口部BH側的端部)中的厚度變厚。藉此,腰圍開口部BH中的緩衝性變高,並且在穿用紙尿褲1時,帶部32的上端部(端部終尾構造)配置在比穿用者的骨盆(胯骨)的頂點位置更靠近上側,具有厚度的部分卡在骨盆的向外突出處,藉此帶部32不易滑落至下方。因此,可使紙尿褲1的貼合性提升。但是,並未侷限於此。亦即,亦可不折返端部32eW1而省略該端部終尾構造。 [0053] 如圖3A所示,吸收性本體10係長邊方向的各端部10eLf、10eLb分別尖端漸細成平面視大致V字形的形狀的薄片狀構件。亦即,吸收性本體10係在長邊方向的各端部10eLf、10eLb,具有對應前述一對前側接合部jf、jf及一對後側接合部jb、jb的形狀。此外,如圖3B所示,同吸收性本體10係具有吸收尿等***液的吸收體11;配置在比同吸收體11更靠近肌膚側的液透過性的頂面薄片12;配置在比同吸收體11更靠近非肌膚側的液不透過性的背面薄片14;及配置在比背面薄片14更靠近非肌膚側的外裝薄片16。 [0054] 接著,該等各構件11、12、14、16係分別以熱熔接著劑或熔接等與以厚度方向鄰接的構件相接合。亦即,在吸收性本體10的長邊方向的各端部10eLf、10eLb中,各構件11、12、14、16分別在積層的狀態下予以接合,針對長邊方向予以固定。藉此,各端部10eLf、10eLb不易以長邊方向(短褲型形狀中的縱向)伸展,吸收性本體10容易收容在內褲之中。關於各端部10eLf、10eLb的伸展的影響,容後說明。其中,以將各構件相接合的接著劑的塗布圖樣而言,可例示Ω圖樣或螺旋圖樣、條紋圖樣等,此不僅針對之後出現的其他接著劑,針對前述之接著劑亦同。 [0055] 此外,當將紙尿褲1穿用在內褲之下時,由於紙尿褲1隱藏在內褲,因此吸收性本體10的長邊方向的尺寸亦即製品長以儘可能縮短為宜。具體而言係以450~750mm為佳。亦即,若未達450mm,無法包覆屁股,助長不安感,若超過750mm,會超過腰圍,穿著時會引起違和感,但是若形成為上述範圍,可防止該等情形,並且紙尿褲1不易從內褲突出。 [0056] 此外,本實施形態之吸收性本體10係在橫向的中央而且長邊方向腹側的端部中,具有以在長邊方向的外側(短褲型形狀中的縱向的上側)以圓弧狀突出的前端突出部10s。當將紙尿褲1形成為短褲型形狀時,在橫向的中央,該前端突出部10s比帶部32的上端(端部32eW1)更朝上側突出(參照圖1等),藉此,使用者容易一看就辨識出紙尿褲1(吸收性本體10)的橫向的中央位置。藉此,當穿用紙尿褲1時,使吸收性本體10容易貼合在身體正確位置,可抑制發生因吸收性本體10在橫向偏移的狀態下被穿用所致之***物橫漏等情形。 [0057] 其中,當開始穿用紙尿褲1的動作時,可確認在腹側及背側中,紙尿褲1是否收容在內褲之中,因此前端突出部10s係以設在吸收性本體10的背側及腹側的兩端部為宜(參照圖2、圖3等)。藉此,穿用紙尿褲1時,容易視認在背側及腹側,紙尿褲1的中央部未從內褲突出,可輕易進行調整為紙尿褲1的全體未從內褲突出的作業。 [0058] 吸收體11係具有:液體吸收性的吸收性芯(未圖示)、及被覆同芯的外周面的未圖示的包芯薄片。吸收性芯係將預定的液體吸收性素材成形為預定形狀者,在圖3A之例中,係在前端與後端具有圓弧狀部分的平面視下呈大致矩形狀的成形體。但是,並非侷限於此。此外,以液體吸收性素材而言,係可例示紙漿纖維等液體吸收性纖維、或高吸收性聚合物(所謂SAP)等液體吸收性粒狀物,但是並非侷限於此。此外,在包芯薄片,係可使用面紙或不織布等液透過性薄片,但是亦可視情況而省略包芯薄片。其中,吸收體11的長邊方向的尺寸較佳為上述製品長的35~85%。其理由係基於若非為35%以上,以吸收體11無法包覆胯間部而會漏洩,另一方面,若超過85%,在穿著時會引起違和感之故。 [0059] 在使吸收體11以橫向伸長的狀態下的寬度W11(亦即,橫向中的吸收體11的一方側之端與另一方側之端之間的距離)係以50mm以上、120mm以下為宜(120mm≧W11≧50mm)。藉由將吸收體11的寬度W11形成為120mm以下,當重疊在內褲之下穿用紙尿褲1時,容易在胯間部將吸收體11不遲緩地收容在內褲之中。此外,藉由將寬度W11形成為50mm以上,容易充分確保用以吸收***物等的面積(吸收容量)。 [0060] 此外,在吸收體11的表面形成有複數溝部17。在本實施形態中,溝部17係具有:第1溝部171、第2溝部172、及第3溝部173(參照圖2)。溝部17係在吸收體11的橫向的中央,沿著長邊方向形成為直線狀。第2溝部172係通過第1溝部171的橫向的中央,一邊與沿著長邊方向的直線(亦即,相當於第1溝部171的延長線的直線)交叉一邊朝向長邊方向的後側(背側)朝橫向的外側擴展而形成為拋物線狀。第3溝部173係在比第2溝部172更靠近長邊方向的前側,形成為一邊與第1溝部171交叉一邊朝向長邊方向的前側(腹側)而朝橫向的外側擴展的拋物線狀。 [0061] 該等溝部17係均藉由預定的壓搾手段來壓搾吸收體11的表面所形成的壓搾部。其中,溝部17並非形成為壓搾吸收體11的壓搾部,亦可形成為開縫。此外,亦可藉由點狀或其他形狀的壓搾部排列複數而形成,而非為如圖2般形成為相連的線狀。 [0062] 第1溝部171係具有作為吸收體11以厚度方向折曲的方式進行誘導的折曲誘導部的功能。具體而言,在穿用紙尿褲1時,在穿用者的***部,沿著第1溝部171,吸收體11折曲成朝穿用者的肌膚側突出的山型,藉此可配合穿用者的身體形狀,使吸收體11適當地變形。其中,本實施形態之紙尿褲1係假想穿用在內褲之下,吸收體11係配置在比內褲更靠近穿用者身體的位置。一般內褲的胯間寬度(胯部寬度)係50~80mm的範圍,因此藉由設置第1溝部171而使吸收體11變形,藉此在胯間部,可在內褲的胯部寬度內,更確實地收納吸收體11。亦即,藉由形成為上述之尺寸範圍(120mm≧W11≧50mm),另外沿著身體的凹凸形狀,使吸收體11立體地變形,可縮窄吸收體11的橫向的實質寬度。藉此,在胯間部,吸收體11不易從內褲更加突出。 [0063] 此外,在比配置有第1溝部171的區域更靠近背側的區域中,使吸收體11變形為山型形狀之力藉由第2溝部172而被傳達至橫向的外側,吸收體11容易在該背側區域被保持為平面狀,因此容易貼合在穿用者的身體背部的平坦部分。此外,吸收體11係容易沿著第3溝部173的拋物線而變形為曲面狀,因此對於穿用者臀部的圓弧,可實現良好的貼合性。 [0064] 頂面薄片12係以不織布等液透過性薄片所形成,在此係使用氣流不織布。亦即,頂面薄片12係相當於「肌膚側不織布」。頂面薄片12的平面尺寸係如圖3A所示,為如由吸收體11的長邊方向的兩側及橫向的兩側突出般的尺寸。接著,橫向突出的部分12eW、12eW係如圖3B所示,朝非肌膚側而且橫向的內側彎曲,藉此,該突出的部分12eW、12eW亦由非肌膚側覆蓋吸收體11的橫向的端部11eW。因此,頂面薄片12的橫向的端部12eW、12eW不會與肌膚磨擦,因此穿著時的違和感會減低。 [0065] 背面薄片14係以聚乙烯薄膜或聚丙烯薄膜等液不透過性薄片所形成。亦即,背面薄片14係相當於「非肌膚側薄膜」。背面薄片14亦為如由吸收體11的長邊方向的兩側及橫向的兩側突出般的平面尺寸的薄片構件。 [0066] 外裝薄片16係由不織布等柔軟薄片所形成。亦即,外裝薄片16係相當於「外裝不織布」。外裝薄片16係如由背面薄片14的長邊方向的兩側及橫向的兩側突出般的尺寸的薄片構件。 [0067] 順帶一提,在以下說明中,有使用所謂「吸收性本體10的肌膚側面」的表現的情形,但是形成該吸收性本體10的肌膚側面的薄片係依同本體10的平面位置而改變。亦即,在存在頂面薄片12的位置,頂面薄片12的肌膚側面形成吸收性本體10的肌膚側面。但是,在不存在頂面薄片12而存在背面薄片14的位置,背面薄片14的肌膚側面形成吸收性本體10的肌膚側面,此外,在頂面薄片12及背面薄片14的兩者均不存在的位置,外裝薄片16的肌膚側面形成吸收性本體10的肌膚側面。 [0068] 在吸收性本體10中的長邊方向的各端部10eLf、10eLb,係分別以覆蓋同吸收性本體10的肌膚側面的方式設有疏水性薄片50、50(在圖3中,參照點模樣的部分)。亦即,在頂面薄片12(肌膚側不織布)的肌膚側積層有疏水性薄片50。吸收性本體10的長邊方向的各端部10eLf、10eLb係在穿用紙尿褲1時,可與穿用者的腹部或臀部相對向的部位,若該等各端部10eLf、10eLb的肌膚側因***液而弄濕時,有使穿用者產生不舒服感之虞。相對於此,在各端部10eLf、10eLb的肌膚側面設置疏水性薄片50,藉此抑制吸收性本體10所吸收的***液返回至肌膚側而滲出的情形,可不易對穿用者帶來不舒服感。 [0069] 其中,頂面薄片12、背面薄片14、外裝薄片16、及疏水性薄片50均如圖4所示,具有在縱向(長邊方向)以比吸收體11的上端11eLf更靠近上方(腰圍側)突出的部分。此外,頂面薄片12、外裝薄片16、及疏水性薄片50係具有以比背面薄片14的上端14eLf更靠近上方(腰圍側)突出的部分。亦即,在本實施形態之紙尿褲1中,在吸收性本體10之中比背面薄片14(非肌膚側薄膜)的腹側的上端14eLf更靠近上側的區域10uf中,具有包含頂面薄片12、外裝薄片16、及疏水性薄片50的至少3層。其中,在圖4中係僅針對長邊方向的腹側,顯示吸收性本體10的剖面構造,但是吸收性本體10針對背側亦具有大致同樣的剖面構造。亦即,吸收性本體10係在比背面薄片14(非肌膚側薄膜)的背側的上端14eLb更靠近上側的區域10ub(均未圖示)中,具有至少3層。 [0070] 接著,在吸收性本體的長邊方向的端部10eLf、10eLb,該等各層(薄片構件)在積層的狀態下彼此接合。若為一般的短褲型紙尿褲,積層的薄片構件彼此係透過夾在其間的彈性構件(絲線橡膠)相接合。亦即,具有積層的薄片構件彼此係在存在彈性構件的部分彼此接合,但是在不存在彈性構件的部分並未彼此接合,薄片構件被拉伸時不相接合的部分容易伸展的構造。相對於此,在本實施形態中,積層的薄片構件彼此以面相接合,因此全體具有不易伸展的構成。 [0071] ===關於紙尿褲1的穿用態樣=== 如上所述,本實施形態之紙尿褲1係可重疊穿用在內褲之下。尤其,當大人由紙尿褲1之上重疊穿用內褲時,不易產生穿用紙尿褲時的違和感,穿用者可以穿用一般內褲的感覺過著日常生活。若連同內褲一起穿用紙尿褲1,預先在內褲的內側(肌膚側)重疊配置紙尿褲1,在腿圍開口部穿過穿用者的腳之後,將紙尿褲1與內褲一起上拉,藉此可不費力地穿用紙尿褲1及內褲。當然,亦可在穿用紙尿褲1之後,從其上方穿用內褲。 [0072] 圖5係顯示由正面(腹側)觀看穿用者穿用紙尿褲1,另外從其上穿用內褲的狀態時的概略圖。在同圖5中,以實線表示內褲,以虛線表示紙尿褲1。圖6係在自然狀態下由正面(腹側)觀看短褲型形狀的紙尿褲1時的概略平面圖。「自然狀態」係指將紙尿褲1放置預定時間時的狀態。例如,將紙尿褲1的帶部32朝橫向的兩外側拉伸,將帶部32及吸收性本體10形成為「伸長的狀態」,使該伸長狀態繼續15秒鐘之後,解除紙尿褲1的拉伸而放置在桌子等平面。接著,以如上所示之平面平放式經過5分鐘後的狀態為自然狀態。圖7係使短褲型形狀的紙尿褲1以縱向及橫向伸長的狀態的概略平面圖。其中,圖7中的「使其伸長的狀態」係與上述「伸長的狀態」同義。此外,帶部32在自然狀態下,係如圖6所示相對橫向呈斜向傾斜,但是在伸長的狀態下,則如圖7所示形成為以橫向筆直延長的形狀。 [0073] 當將紙尿褲1與內褲重疊穿用時,如圖5的粗虛線箭號所示,進行抓住紙尿褲1的帶部32的橫向兩側部分及內褲的側邊部而以斜上方向拉伸的動作。在紙尿褲1中,配置在橫向兩側的一對帶部32、32分別藉由前側接合部jf、jf(後側接合部jb、jb),對吸收性本體10斜向接合,因此在自然狀態下,帶部32的長邊方向朝向斜上方向。具體而言,如圖6所示,若將帶部32的橫向外側端而且縱向上側端設為帶上端32eou時,在自然狀態下,上端32eou的位置係成為比吸收性本體10的上端(前端突出部10s的上端)的位置更靠近縱向的上側。此外,若將帶部32的橫向外側端而且縱向下側端設為帶下端32eod時,在自然狀態下,下端32eod的位置係成為比上端32eou的位置更靠近橫向的外側。藉由該構成,自然狀態下的帶部32相對於吸收性本體10,朝向橫向的外側而且縱向的上側呈斜向。 [0074] 接著,在帶部32,沿著長邊方向設有絲線橡膠33,因此藉由將帶部32以斜上方向拉伸之力,該絲線橡膠33以長邊方向伸長,帶部32展現伸縮性。藉由該伸縮性,透過帶部32及前側接合部jf,吸收性本體10由橫向的兩側以斜上方向效率佳地拉伸向上,吸收性本體10容易一邊朝寬度方向擴幅一邊貼合在穿用者的胯間部。 [0075] 在一般的紙尿褲中,以彈性構件橫向伸縮的方式作配置,因此若欲以斜方向施力時,必須要有以橫向伸展之後再以縱向上拉的動作,帶構件的任何部位容易產生變形。另一方面,在紙尿褲1的構成中,在自然狀態下,帶部32朝向斜上方,因此抓住帶部32上拉時,力容易以斜向施加,以斜向上拉時,力亦不會集中在局部,力容易傳至位於帶部32的延長線上的吸收性本體10的全域。亦即,傳至藉由絲線橡膠33所致之伸縮力不易伸展的吸收性本體10,因此容易將不易伸展的部分上拉。此外,穿用紙尿褲1時以手抓住的部分亦即帶部32的橫向兩端部亦形成斜向(基於上端32eou及下端32eod的位置關係),因此容易將帶部32更加上拉。 [0076] 其中,一般內褲係由易以縱向及橫向伸縮的素材(例如聚胺酯彈性纖維等)所形成,因此若紙尿褲的帶部未具有充分的伸縮性,當將紙尿褲與內褲重疊穿用時,帶部的伸縮無法追隨內褲的伸縮而難以一起穿用兩者。此外,一般的用後即棄紙尿褲係在自然狀態下,帶部未朝向斜方向,將吸收性本體與帶部相接合的接合部亦未朝向斜方向。因此,將帶部伸展之力雖然容易傳至橫向,但是並不易傳至縱向,不易與內褲之力連動。 [0077] 相對於此,在本實施形態之紙尿褲1中,斜向形成接合部jf、jb,帶部32在自然狀態下朝向斜方向,另外帶部32的橫向端部亦朝向斜向,因此力容易朝斜方向施加。藉此,當將縱向或橫向均可伸縮的內褲伸展時所發生的斜上上拉的力容易與帶部32連動,結果可不會從內褲脫離地穿用紙尿褲1。 [0078] 此外,將帶部32的縱向中的寬度的最小值設為h32(參照圖7)。亦即,h32係縱向中的帶部32的一方側之端與另一方側之端之間的距離的最小值。在紙尿褲1中,係規定該距離h32成為50mm以上100mm以下(100mm≧h32≧50mm)。藉由將h32設為100mm以下,當將紙尿褲1與內褲重疊穿用時,帶部32不易從內褲的側邊部分突出。另一方面,藉由將h32形成為50mm以上,可充分確保穿用者的肌膚與帶部32的接觸面積,藉由帶部32與穿用者的肌膚的摩擦作用,容易抑制帶部32滑落或變圓而變細的情形。此外,成人抓東西時,將食指與大拇指擴展時的長度為100mm左右,因此若為如上所示之尺寸,成人容易單手抓住帶部32,可安定地進行將帶部32朝斜上方向拉伸的動作。藉由該等,可提高帶部32的貼合性,並且不易從內褲之下突出。 [0079] 將帶部32朝斜上方拉伸向上後,如圖5之粗實線箭號所示,將吸收性本體10的腹側的端部10eLf及背側的端部10eLb(圖5中並未圖示)朝上方上拉,進行使吸收體11貼合在胯間部的動作。在該上拉動作中,大多為吸收性本體10的端部10eLf(10eLb)之中上端(邊緣)部被抓住而拉伸的情形,但是若紙尿褲由不織布等柔軟素材所形成,有被拉伸的部分伸展的情形。尤其,本實施形態之紙尿褲1係假想重疊穿用在內褲之下,因此若端部10eLf(10eLb)伸展,有該伸展的部分從內褲突出之虞。此外,因不織布伸展,無法將吸收體11牢牢地上拉,有貼合性惡化之虞。 [0080] 相對於此,在紙尿褲1中,在吸收性本體10的長邊方向的端部10eLf(10eLb)中,使預定數的薄片構件積層來提高強度,藉此不易伸展該區域。具體而言,如圖4所示,在端部10eLf中,以具有至少3層以上的積層構造的方式構成吸收性本體10。例如,在縱向,在比背面薄片14(非肌膚側薄膜)的上端14eLf更接近上側的區域10uf中,具有由頂面薄片12(肌膚側不織布)、外裝薄片16(外裝不織布)、及疏水性薄片50所成之3層。此外,在縱向,在背面薄片14的上端14eLf與吸收體11的上端11eLf之間的區域10mf中,除了上述3層之外,具有包含背面薄片14(非肌膚側薄膜)的4層,因此強度更加提高。此外,除此以外,亦可積層其他不織布等。 [0081] 圖8係顯示針對紙尿褲的拉伸強度進行試驗的結果的圖。在同圖8中係顯示將本實施形態之紙尿褲1及藉由不織布所形成的2種類的既製品的紙尿褲(習知品)作為試樣1、試樣2,將吸收性本體10的長邊方向的端部區域(相當於區域10uf的區域)朝縱向的上側拉伸時的荷重與伸展的關係。 [0082] 試樣1及試樣2係均具有橫向呈連續的帶構件,相當於端部10eLf(在紙尿褲1中為區域10uf)的區域中的薄片構件的積層數為2層以下的用後即棄紙尿褲。更具體而言,試樣1係在橫方展現伸縮性的彈性構件(絲線橡膠)沿著橫向作配置,該彈性構件係在橫向的中央部(相當於區域10uf的部分)具有非連續部分。接著,在該非連續部分中,夾著彈性構件作積層的2片不織布間形成為非接合。另一方面,試樣2係在橫方展現伸縮性的彈性構件(絲線橡膠)沿著橫向連續作配置,夾著該彈性構件作配置的2片不織布透過彈性構件而在橫向的中央部(相當於區域10uf的部分)相接合。 [0083] 關於如上所示之試樣1、試樣2、及紙尿褲1,將分別相當於區域10uf的區域以拉伸試驗機抓住進行拉伸,且測定使荷重增加時的伸展量。亦即,在試樣1中係針對2片薄片構件未被接合的部分進行拉伸試驗,在試樣2中係針對2片薄片構件被間歇接合的部分進行拉伸試驗,在紙尿褲1中,係針對在縱向(長邊方向)接合有3片薄片構件的部分進行拉伸試驗。結果,任一者均荷重增加且伸展量增加,在試樣1中,荷重50N下的伸展量為約7mm,此外,伸展限度時的荷重為約70N,難以進行此之後的正確測定。接著,在試樣2中,荷重50N下的伸展量為約16mm,而且伸展限度時的荷重為約100N,難以進行其之後的正確測定。另一方面,在本實施形態之紙尿褲1中,荷重50N下的伸展量為1mm以下,荷重100N下的伸展量為約2mm,接著,伸展限度時的荷重為約300N。 [0084] 如上所示,清楚可知在紙尿褲1中,在吸收性本體10的端部10eLf(10eLb)中,因具有分別接合至少3層以上的薄片構件的積層構造,端部10eLf(10eLb)的強度與習知品相比較為極高,對於拉伸,具有不易伸展的構造。因此,即使在穿用紙尿褲1時,區域10uf朝上側被拉伸的情形下,亦抑制該區域伸展,吸收性本體10不易從內褲突出,此外,將吸收體11牢牢地上拉,藉此實現良好的貼合性。 [0085] 此外,在紙尿褲1中,縱向中的區域10uf的長度L10uf成為20mm以上。亦即,在縱向中,在前述吸收性本體10之中比背面薄片14(非肌膚側薄膜)的上端14eLf更靠近上側,薄片構件積層3層以上的區域的長度成為20mm以上(L10uf≧20mm)。如圖7的斜線部所示,區域10uf係在吸收性本體10的上端而且被夾在一對前側接合部jf、jf之間的區域,穿用紙尿褲1時,當穿用者拉伸吸收性本體10時,容易用手指抓住的區域。因此,藉由將該區域形成為3層構造,可一邊確保充分強度,一邊藉由形成為容易抓住的大小的區域,穿用者可輕易進行上拉吸收性本體10的動作。其中,在吸收性本體10的縱向的上端設有上述之前端突出部10s,但是在本實施形態中,區域10uf之中除了前端突出部10s之外的部分的長度成為20mm以上(參照圖7)。 [0086] 此外,在縱向,前端突出部10s比前側接合部jf(後側接合部jb)的上端(亦即帶部32的上端位置)更靠近上側突出的長度L10s係1mm以上、5mm以下(5mm≧L10s≧1mm)。若L10比1mm為更短,前端突出部10s本身變得不易視認,難以辨識紙尿褲1的橫向的中央位置。此外,若L10比5mm為更長,前端突出部10s捲曲或折曲,變得無法發揮作為表示橫向的中央位置的記號的功能。此外,若L10變長,有前端突出部10s從內褲突出之虞。相對於此,藉由形成為5mm≧L10s≧1mm,不會有從內褲突出的情形,而可容易辨識橫向的中央位置。 [0087] 此外,吸收性本體10之中區域10uf的縱向中的長度L10uf係比帶部32的上側端部32eW1被折返的部分(上述的端部終尾構造)的縱向中的長度L32eW1為更長。藉此,吸收性本體10的區域10uf朝上側拉伸之力容易透過前側接合部jf、jf而傳達至帶部32的上側端部32eW1。亦即,帶部32的上側端部32eW1的縱向中的全域容易連同吸收性本體10的區域10uf一起被上拉至上側。因此,藉由進行將吸收性本體10的上側的端部10eLf上拉的動作,可調整包含帶部32的腰圍開口部BH的全體的位置(高度)。藉此,紙尿褲1的貼合性提升,並且紙尿褲1的腰圍開口部BH不易從內褲突出。 [0088] 此外,當由橫向觀看紙尿褲1時,在吸收性本體10的腹側中的上端的區域10uf、及吸收性本體10中的上端的區域10ub係分別形成以厚度方向突出的皺褶。此在腰圍開口部BH之中在帶部32係沿著其長邊方向作用藉由絲線橡膠33所致之伸縮性,相對於此,在吸收性本體10的上端的區域10uf、10ub並未作用伸縮性之故。亦即,在區域10uf、10ub的橫向兩側配置具伸縮性的帶部32,透過接合部jf、jf由兩側斜向拉伸,藉此在端部區域10uf、10ub的平面形狀容易發生變形,因該變形,容易形成皺褶。該皺褶的大小係依接合部jf、jb的傾斜角度或區域10uf、10ub的縱向中的長度L10uf、L10ub而改變,但是在本實施形態中,形成在吸收性本體10的腹側的端部10eLf的皺褶的厚度方向中的高度的最大值小於形成在腹側的端部10eLf的皺褶的厚度方向中的高度的最大值。藉此,當將紙尿褲1重疊穿用在內褲之下時,因該皺褶的影響,抑制在腹側,內褲在厚度方向的非肌膚側被過度上舉、或紙尿褲1在內褲之下混亂的情形,容易獲得良好的貼合性。此外,在腹側縮小皺褶,藉此在內褲之下穿用紙尿褲1較不易顯眼。 [0089] ==其他實施形態=== 以上說明本發明之實施形態,惟上述之實施形態係用以易於理解本發明者,並非為用以限定本發明來作解釋者。此外,本發明在未脫離其要旨的情形下,可進行變更或改良,並且在本發明中包含其等效物,自不待言。例如,可進行如以下所示之變形。 [0090] 在上述之實施形態中,在圖3A的展開狀態下的吸收性本體10的橫向的兩側的位置,未設有用以防止橫漏的所謂立體摺邊,但是亦可視情況加以設置。但是,較佳為如上述之實施形態所示不設置立體摺邊為佳。詳細內容如下所示。 [0091] 首先,為了設置立體摺邊,將沿著長邊方向的絲線橡膠等彈性構件在以同方向伸長的狀態下被固定的一對立體摺邊薄片,分別固定在吸收性本體10的橫向的兩側。此外,關於在同立體摺邊薄片中比被固定在吸收性本體10的部分更靠近橫向的內側的部分,其長邊方向的兩端部亦被固定在吸收性本體10。接著,藉此,在同內側的部分未被固定在吸收性本體10的長邊方向的中央部根據上述彈性構件的收縮力而豎立,藉此,該中央部發揮作為立體摺邊的功能。但是,在此,被固定的上述兩端部係在肌膚側凸起,因此容易與穿用者的臀部等摩擦,結果,失去穿著感。此外,在外觀上亦容易想起像紙尿褲。因此,較佳為若不設置立體摺邊較佳。 [0092] 在上述之實施形態中,並未說明前側接合部jf及其近傍部分的剖面形狀。因此,在此參照圖9A及圖9B加以說明。圖9A係圖7中的D-D剖面圖。圖9B係圖7中的E-E剖面圖。亦即,圖9A係顯示前側接合部jf之中縱向的兩端部(腰圍開口部BH及腿圍開口部LH附近)的剖面,圖9B係顯示前側接合部jf之中縱向的中間部附近的剖面。如圖9A及圖9B所示,前側接合部jf係以朝前後方向的前側(非肌膚側)起立的方式突出形成。接著,在前側接合部jf的吸收性本體10的非肌膚側存在有疏水性薄片50,因此根據同薄片50的剛性,以吸收性本體10與前側接合部jf的交界部分的角度θ1成為鈍角,帶部32與前側接合部jf的交界部分的角度θ2成為銳角的方式,前側接合部jf係成為倒向橫向的外側的狀態。 [0093] 此外,在前側接合部jf的外緣部係設有帶部32與吸收性本體10不相接合的乾邊jde。接著,該乾邊jde的寬度(亦即以比帶部32與吸收性本體10相接合的部分更靠近非肌膚側突出的部分的長度)係在縱向的兩端部為最短,在縱向的中央部為最長。乾邊jde係在紙尿褲1的製造工程中,當將以厚度方向重疊的吸收性本體10及帶部32沿著前側接合部jf切斷時,藉由將由該前側接合部jf的端緣分離預定距離的位置切斷而形成。此時,為了防止將前側接合部jf本身切斷,一般藉由將由前側接合部jf的端緣分離一定程度的位置切斷而將乾邊jde儘可能形成較大(長)。但是,本實施形態之紙尿褲1係假想重疊穿用在內褲之下,因此若乾邊jde過大,容易干擾內褲。尤其,在腰圍開口部BH或腿圍開口部LH附近,若乾邊jde形成較大,因穿用時緊固在內褲,有成為使腰圍或腿圍產生違和感的要因的情形。因此,在紙尿褲1中,以前側接合部jf的長邊方向的兩端部中的乾邊jde的寬度,比前側接合部jf的長邊方向的中央部中的乾邊jde的寬度為更短的方式,形成乾邊jde。藉此,在穿用紙尿褲1時,可在穿用者不易發生腰圍或腿圍的違和感。其中,關於後側接合部jb亦同。[0009] At least the following matters are apparent from the description of the specification and the accompanying drawings. [0010] A pants-type diaper having a waist-shaped opening portion and a pair of leg-opening portions in a longitudinal direction and a lateral direction intersecting each other, comprising: an absorbent body comprising: An absorbent body that absorbs excretion liquid, a non-woven fabric that is disposed on the skin side that is closer to the skin side than the absorbent body, and a liquid-impermeable non-skin side film that is disposed closer to the non-skin side than the absorbent body, and is disposed. An outer nonwoven fabric that is closer to the non-skin side than the non-skin side film; and a belt portion that is disposed on each of the lateral sides and that connects the end portions of the absorbent body in the longitudinal direction, the belt The second pair of joint portions which are inclined toward the lower side of the longitudinal direction and the lateral outer side by the waist opening portion toward the leg-opening portion are joined to the absorbent body, and one of the belt portions in the longitudinal direction The minimum value of the distance between the end of the side and the end of the other side is 50 mm or more and 100 mm or less. In the longitudinal direction, the absorbent body is thinner than the non-skin side. The upper end of the film is closer to the upper side, and has at least three layers including the layer of the skin side nonwoven fabric and the layer of the outer nonwoven fabric. [0011] When the pant-type diaper as described above is worn over the panty, it is easy to stretch the belt portion obliquely upward together with the underpants, and the fit is easily improved. Further, the width of the belt portion is limited to a predetermined range, so that the belt portion is easily caught, and the belt portion does not easily protrude from the side portion of the underwear after wearing. Further, the upper end portion of the absorbent body has a three-layer structure, so that the strength of the portion becomes high, and when the absorbent body is pulled up, the portion is not easily stretched. Therefore, when the panty is worn over, the upper end portion of the absorbent body is less likely to protrude from the undergarment, and the absorbent body is firmly pulled up, whereby good fit can be achieved. [0012] In the pants-type diaper, it is preferable to have a liquid-impermeable hydrophobic sheet disposed closer to the skin side than the skin-side non-woven fabric. [0013] With the pants-type diaper as described above, a hydrophobic sheet is provided on the skin side surface of the longitudinal end portion of the absorbent body, thereby suppressing the excretion liquid absorbed by the absorbent body from returning to the skin side and oozing out. It is not easy to bring uncomfortable feeling to the wearer. Further, in the longitudinal end portion of the absorbent body, the strength of the region can be improved by laminating with the skin side non-woven fabric or the outer nonwoven fabric. [0014] In the pants-type diaper, it is preferable that the amount of stretch when the region of the absorbent body that is closer to the upper side than the upper end of the non-skin side film is stretched toward the upper side in the longitudinal direction by a force of 50 N is 1.0. Below mm. [0015] With the pants-type diaper as described above, when the diaper is worn, even in a case where the upper side of the absorbent body is stretched upward than the upper end of the non-skin side film, the area is not easily Stretching, suppressing the upper end portion of the absorbent body from being protruded from the undergarment. Further, by stretching the region, the absorbent body can be firmly pulled up, so that good fit can be achieved. In the pants diaper, it is preferable that the length in the longitudinal direction of the region closer to the upper side than the upper end of the non-skin side film in the absorbent body is 20 mm or more. [0017] With the pants-type diaper as described above, the region of the absorbent body that is closer to the upper side than the upper end of the non-skin side film is easy to grasp with the fingers when the wearer stretches the absorbent body when wearing the diaper. Therefore, the wearer can easily perform the operation of pulling up the absorptive body by forming a region of a size that is easy to grasp while sufficiently securing the strength of the region. [0018] In the pants-type diaper, it is preferable that the belt portion has an end-end structure in which the upper end portion is folded back in the longitudinal direction, and an area of the absorbent body that is closer to the upper side than the upper end of the non-skin side film. The length in the aforementioned longitudinal direction is shorter than the length in the aforementioned longitudinal direction of the portion of the belt portion having the aforementioned end end tail configuration. [0019] With the pants-type diaper as described above, the upper end region of the belt portion is stretched to a region closer to the upper side than the upper end of the non-skin side film, and is easily pulled up to the upper side together. . Therefore, by the operation of the pull-up absorbent main body, it is easy to adjust the position (height) of the entire waist opening portion including the belt portion, and the fit is improved, and the diaper is less likely to protrude from the underwear. [0020] In the pants-type diaper, it is preferable that the maximum value of the height of the wrinkles formed in the region on the ventral side of the absorbent body in the longitudinal direction of the upper end of the non-skin side film is On the back side of the absorbent body, the maximum value of the height of the wrinkles formed in the region in which the longitudinal direction is closer to the upper side than the upper end of the non-skin side film is smaller. [0021] With the pants-type diaper as shown above, when the diaper is overlapped and worn under the undergarment, the ventral side is suppressed, the underpants are excessively lifted to the non-skin side in the thickness direction, and the diaper is confused under the underpants. In the case, it is easy to obtain good fit. In addition, it is less noticeable to wear a diaper under the underpants. In the pants-type diaper, it is preferable that the front end of the longitudinal direction and the back side of the absorbent body have a front end projecting portion that protrudes upward in the longitudinal direction at the center of the longitudinal direction and the center of the lateral direction. [0023] With the pants-type diaper as shown above, the user can easily recognize the lateral center position of the diaper at a glance. Thereby, when the diaper is worn, the absorbent body can be easily attached to the correct position of the body, and the leakage of the excrement due to the wearing of the absorbent body in the laterally displaced state can be effectively suppressed. In the pants-type diaper, it is preferable that the front end projecting portion has a length that protrudes from the upper end of the joint portion in the longitudinal direction by 1 mm or more and 5 mm or less. [0025] With the pants-type diaper as described above, since the protruding length of the distal end protruding portion is set to 1 mm or more, it is suppressed that the distal end protruding portion becomes difficult to be visually recognized. Next, by forming the protruding length of the distal end protruding portion to 5 mm or less, it is possible to suppress the front end protruding portion from being curled or bent or protruding from the undergarment. Thereby, the front end protruding portion easily functions as a symbol indicating the center position in the lateral direction. In the pants-type diaper, it is preferable that the belt portion has a plurality of elastic members that expand and contract along a longitudinal direction of the belt portion, and the elastic member is one end of the belt portion in the longitudinal direction to the other One end is continuously configured. [0027] With the pants-type diaper as described above, since the elastic member does not have a discontinuous portion with respect to the longitudinal direction, there is no possibility that the force for stretching the belt portion in the oblique direction is broken on the way The member exhibits stretchability over the entire length of the belt portion in the longitudinal direction. Thereby, the effect of pulling up the absorbent body is improved, and the fit of the diaper can be further improved. [0028] In the pants-type diaper, it is preferable that the joint portion is provided to be erected on a non-skin side, and the end portion of the non-skin side is provided such that the absorbent body and the belt portion are not joined to each other. In the dry side, the width of the dry side in the both end portions in the longitudinal direction of the joint portion is shorter than the width of the dry side in the center portion in the longitudinal direction of the joint portion. [0029] With the pants-type diaper as described above, the width of the dry side is reduced in the vicinity of the waist opening or the leg opening, thereby suppressing the interference between the underwear and the joint, and the wearer can be worn when wearing the diaper. It is not easy to produce a sense of violation of waist circumference or leg circumference. In the pants type diaper, it is preferable that the lateral outer end of the belt portion and the longitudinal upper end are located closer to the upper side in the longitudinal direction than the upper end of the absorbent body in a natural state. [0031] With the pants-type diaper as shown above, the belt portion is inclined upward from the natural state, so when the belt portion is grasped and pulled up, the force is easily applied obliquely, and the force is easily transmitted to the absorbent body. Global. Thereby, the belt portion is easily pulled up obliquely upward, and the absorbent body is also easily stretched by being pulled up while being interlocked with the belt portion. Therefore, it is easy to improve the fit of the diaper. [0032] In the pants type diaper, preferably, in a natural state, the lateral outer end of the belt portion and the longitudinal lower end are located at a position other than the lateral outer end of the belt portion and the longitudinal direction. The position of the upper end is closer to the outer side of the aforementioned lateral direction. [0033] With the pants-type diaper as described above, the portions that are grasped by the hand, that is, the lateral end portions of the belt portion are formed obliquely, so that it is easy to grasp the belt portion and pull up. [0034] Further, a pants-type diaper having a waist-opening portion and a pair of leg-opening portions and a pair of pants-type diapers which are worn under the undergarments, which are formed in a longitudinal direction and a lateral direction which intersect each other, is characterized by The absorbent body is provided with an absorbent body that absorbs excretion liquid, a skin-side non-woven fabric that is disposed on the skin side closer to the skin than the absorbent body, and is disposed closer to the non-skin side than the absorbent body. a liquid-impermeable non-skin side film and an outer nonwoven fabric disposed closer to the non-skin side than the non-skin side film; and a belt portion disposed on each of the lateral sides, wherein the absorbent body is The end portions of the longitudinal direction are connected to each other, and the belt portion is a pair of joint portions that are inclined toward the lower side of the longitudinal direction and the lateral outer side by the waist opening portion toward the leg-opening portion, and the absorbent body The minimum value of the distance between the end of one side of the belt portion and the end of the other side in the longitudinal direction is 50 mm or more and 100 mm or less, the belt portion, and the aforementioned The lower part of the absorbent body is adjusted to a size hidden in the position of the aforementioned undergarment after wearing the aforementioned undergarment. [0035] With the pants-type diaper as described above, the underwear is superimposed on the diaper, whereby the feeling of discomfort when wearing the diaper is less likely to occur, and the wearer can feel the daily life by wearing the general underwear. At this time, the diaper is hidden under the underpants and is not conspicuous, so the wearer is not easy to realize that the diaper is being worn, and it is not easy to cause mental uneasiness. [0036] Further, a method of wearing a pants-type diaper having a waist opening portion and a pair of leg-opening portions, and an absorbent body, is provided. An absorbent body that absorbs excretion liquid, a skin-side non-woven fabric that is disposed on the skin side closer to the skin than the absorbent body, and a liquid-impermeable non-skin side film that is disposed closer to the non-skin side than the absorbent body. And an outer nonwoven fabric disposed closer to the non-skin side than the non-skin side film; and a belt portion disposed on each of the lateral sides to connect the end portions of the absorbent body in the longitudinal direction a pair of joint portions which are inclined toward the front leg opening portion and the lateral outer side by the waist opening portion, and the pair of joint portions are joined to the absorbent body, and the pants type diaper is worn by the method. The pants-type diaper is placed on the skin side of the underpants; the pants-type diaper and the leg-opening portion of the panty are passed through the wearer's foot. Thereafter, the belt portion is pulled up obliquely upward together with the side portions of the aforementioned underpants; and in the ventral side and the back side, together with the aforementioned longitudinal upper end portion of the aforementioned undergarment, the aforementioned longitudinal upper end portion of the aforementioned absorbent body Pull up from above. [0037] With the wearing method of the pants-type diaper as described above, the underwear is superimposed on the diaper, whereby the feeling of discomfort when wearing the diaper is less likely to occur, and the wearer can feel the daily life by wearing the general underwear. Next, by wearing the underpants and the diaper together, the position of the diaper is not easily deviated from the underpants, and in addition, the diaper can be worn without protruding from under the underpants. [0038] === Embodiments === A disposable diaper 1 (hereinafter also referred to as a diaper 1) which is an example of the absorbent article of the present embodiment will be described. The diaper 1 of the present embodiment can be worn under the undergarments, and in this case, the respective portions can be configured so as not to be worn from the underpants. Fig. 1 is a schematic perspective view of a diaper 1. The diaper 1 has been formed into a pants-type state as shown in Fig. 1 at the time of wearing. Next, in the pants type, the same diaper 1 has a longitudinal direction and a lateral direction and a front-rear direction orthogonal to each other. Among them, when the same diaper 1 is worn, the longitudinal direction is mostly in the up and down direction. Therefore, the vertical direction is also referred to as "up and down direction" below. Further, in the up and down direction, the upper side corresponds to the waist side of the wearer, and the lower side corresponds to the underarm side of the wearer. On the other hand, regarding the front-rear direction, the front side corresponds to the ventral side of the wearer, and the rear side corresponds to the back side of the wearer. [0039] In the same pants type, the diaper 1 has a belt-shaped absorbent body that is folded in a substantially central position CLL10 (FIG. 2A) in the same longitudinal direction along the longitudinal direction in the vertical direction. 10; each of the belt portions 32, 32 that connect the end portions 10eLf, 10eLb in the longitudinal direction of the absorbent body 10 to each other in the lateral direction; and in the lateral direction of the absorbent body 10, respectively The leg flange portions 37 and 37 of the leg-opening portion LH are formed on both sides. That is, one end portion 10eLf of each of the end portions 10eLf and 10eLb of the absorbent body 10 is located above and on the front side, and the other end portion 10eLb is located on the upper side and the rear side. Further, on the front side of the diaper 1, the front side joint portions jf, jf (corresponding to the joint portion) which are inclined from the upper side in the longitudinal direction and the outer side in the lateral direction are provided in a lateral direction, and are similarly arranged in the diaper. The rear side of the first side is also provided with a pair of lateral joint portions jb, jb (corresponding to the joint portion) which are inclined from the upper side toward the lower side in the longitudinal direction and which are inclined outward from the inner side in the lateral direction. Next, the end portions 10eLf of the absorbent body 10 on the front side are joined to the lateral end portions 32eLf, 32eLf of the respective belt portions 32, 32 by the pair of front side joint portions jf, jf of the former, and the legs on the front side are joined The end portions 37eLf, 37eLf of the hemming portions 37, 37 are joined to the lateral end portions 32eLf, 32eLf of the respective belt portions 32, 32. Further, similarly, the end portion 10eLb of the absorbent body 10 located on the rear side is engaged with the lateral end portions 32eLb, 32eLb of the respective belt portions 32, 32 by the pair of rear side joint portions jb, jb of the latter, and The end portions 37eLb, 37eLb of the leg flange portions 37, 37 on the rear side are joined to the lateral end portions 32eLb, 32eLb of the respective belt portions 32. Then, in the same pants type state, the waist opening is formed in the upper portion of the diaper 1 by the respective end portions 10eLf and 10eLb of the absorbent main body 10 and the upper end portions of the respective belt portions 32 and 32. BH. Further, a pair of leg-opening portions LH and LH are formed on both sides in the lateral direction by the laterally outer end portions of the leg-folding portions 37 and 37 and the lower end portions of the respective belt portions 32 and 32. Further, each of the belt portions 32 is arranged such that a plurality of the thread rubbers 33, 33, ... are arranged in the vertical direction in the vertical direction, whereby the belt portions 32 are provided with lateral stretchability. On the other hand, each of the leg cuff portions 37 is also arranged in the lateral direction so as to be disposed along the plurality of the thread rubbers 38 and 38 in the longitudinal direction of the absorbent body 10, whereby the leg cuff portions 37 are given the up and down direction. Scalability. Then, based on the stretchability, the waist opening portion BH and the leg circumference opening portion LH of the diaper 1 are respectively attached to the waist circumference or the leg circumference of the wearer. Further, as shown in FIG. 3, the belt portion 32 is a portion in which the waist opening portion BH is formed (the lateral outer end portion of the belt portion 32 in Fig. 3) extends straight, and the leg opening portion LH is formed in contrast thereto. The portion (the lateral inner end portion of the belt portion 32 in Fig. 3) is a curve (R shape) that is convex toward the waist opening portion BH side. Thereby, in the state in which the pants type is formed, the leg-opening portion LH is easily curved along the circumference of the panty leg, and the diaper 1 is less likely to protrude from the underwear even in the case of wearing under the underpants. In addition, the wearing action of the diaper 1 (details of the wearing operation will be described later) by the curved shape as described above, when the belt portion 32 is pulled up obliquely upward, the force obliquely upward is easily applied to the shorts. The lateral end portion of the belt portion 32 in the shape of the belt can smoothly pull up the belt portion 32 obliquely upward. The diaper 1 shown above is formed in the final stage of the manufacturing process thereof in the state of the extended flat plate as shown in FIGS. 2A and 2B. 2A is a schematic plan view of the diaper 1 in a state in which the stretched flat plate is viewed from the side of the belt portion 32, and FIG. 2B is a cross-sectional view taken along line B-B in FIG. 2A. In Fig. 3A, in the diaper 1 in the extended flat state of Fig. 2A, the respective joints of the front side joint portions jf and jf and the rear side joint portions jb and jb are unwound to see the skin side surface of the absorbent body 10, respectively. A schematic plan view showing a state in which the belt portions 32 and 32 are opened outward in the lateral direction, and Fig. 3B is a cross-sectional view taken along line BB in Fig. 3A. Fig. 4 is a schematic cross-sectional view showing the structure of a C-C cross section of Fig. 3A. In addition, the wavy lines shown in FIGS. 2B, 3B, and 4 are those in which the adhesive is displayed in a mode, and the portion shown in the hatched pattern of the left oblique line is displayed in a mode to show the welded portion. [0045] The diaper 1 of the stretched flat state of FIG. 2A corresponds to the diaper 1 of the pants-type state of FIG. 1 in such a manner that the absorbent body 10 is folded in the opposite direction, and the absorbent body 10 is parallel to the longitudinal direction thereof. The state in which both sides of the front-rear direction are stretched and stretched. Next, in the extended flat state, as shown in FIG. 2B, the respective skin sides of the absorbent body 10 and the leg folded portions 37, 37 are formed such that the respective belt portions 32, 32 overlap. By the way, when the end portions 32eW1 and 32eW1 of the inner side of the pair of belt portions 32 and 32 in the diaper 1 in the state of the flat plate are stretched outward in the lateral direction, respectively, the absorbent property is absorbed. The main body 10 is folded in half at a substantially central position CLL10 in the longitudinal direction, and the diaper 1 is in a pants-type state as shown in FIG. Further, in the extended flat state, the diaper 1 has a longitudinal direction and a lateral direction and a thickness direction which are orthogonal to each other. Then, the longitudinal direction is parallel to the longitudinal direction of the pants-type state. In addition, the one side and the other side of the longitudinal direction correspond to the ventral side of the wearer, that is, the front side and the back side, that is, the rear side. Therefore, the one side and the other side are also referred to as "front side". And "back side". Further, in the extended flat state, the longitudinal direction of the diaper 1 is aligned with the longitudinal direction of the absorbent body 10, the belt portion 32, and the leg folded portion 37. Therefore, the following is not referred to as "longitudinal direction". On the other hand, the horizontal direction is the same as the lateral direction of the pants type state, and hereinafter simply referred to as "horizontal direction". Further, regarding the thickness direction, the side contacting the wearer's body is also referred to as "skin side", and the opposite side is also referred to as "non-skin side". [0047] Further, in the state of the extended flat plate, the diaper 1 is formed in a state of being elongated in the longitudinal direction, but the so-called "elongated state" means resistance to each elastic member (for example, a belt portion) disposed in the diaper 1. When the diaper 1 is elongated in the longitudinal direction by the contraction force by the thread rubber 33 of the 32 or the thread rubber 38 of the leg hem portion 37, the diaper 1 is elongated until the portion where the elastic members are disposed substantially becomes invisible The state of the degree of pleats or hem. Therefore, the shape of the diaper 1 in a state of being elongated in the longitudinal direction is the same as the shape of the diaper 1 which is flatly extended in a state where the contraction force by the respective elastic members is not exhibited. [0048] Hereinafter, the configuration of the same diaper 1 will be described with reference to the diaper 1 in the state in which the flat plate is extended. In the extended flat state of FIGS. 2A and 2B, the leg folded portions 37, 37 are respectively located on both sides of the lateral direction of the absorbent body 10, and are overlapped on the skin side of the absorbent body 10 and the leg folded portions 37. In the manner of the skin side of 37, the pair of belt portions 32, 32 are arranged in the lateral direction. [0049] The belt portion 32 and the leg folded portion 37 are formed by the same sheet member 30. In other words, as shown in FIG. 3A and FIG. 3B, the sheet members 30 and 30 are disposed one by one on both sides in the lateral direction of the absorbent body 10, and the laterally inner end portions 30eW of the sheet members 30 and 30, The 30eW is joined to each of the end portions 10eW and 10eW in the lateral direction of the absorbent body 10, respectively. In detail, the inner end portion 30eW is interposed between the top sheet 12 and the back sheet 14 or the outer sheet 16 which will be described later, which constitutes the absorbent body 10, and is joined by an adhesive or welding. Sheets 12, 14, 16. Further, as shown in FIG. 3B, a turn-back line FL along the longitudinal direction is set between the portion which becomes the belt portion 32 in the sheet member 30 and the portion which becomes the leg-folded portion 37. Next, each of the sheet members 30 is formed with a leg-opening portion LH penetrating in the thickness direction so as to straddle the return line FL in the lateral direction. Therefore, the sheet member 30 is folded back toward the inner side in the lateral direction by the return line FL, whereby the belt portion 32 and the leg folded portion 37 are formed. Next, the absorbent body 10 and the leg folded portions 37 and 37 are joined to the respective belt portions 32 and 32 by the front side joint portions jf and jf and the rear side joint portions jb and jb shown in FIG. 2A, and are fixed to the above. In the folded-back state, the diaper 1 in the above-described extended flat state is formed. [0050] wherein, the formation of the front side joint portion jf and the rear side joint portion jb is performed by, for example, a heat sealing seal or a ultrasonic sealing or the like, or a subsequent treatment by an adhesive agent, where the welding is performed. Processing to proceed. Further, as shown in FIG. 3B, the sheet member 30 is formed by, for example, forming the soft sheets 30a and 30a such as non-woven fabric in a thickness direction in two pieces, and then, in the two overlapping sheets 30a, Between the 30a, the thread rubbers 33, 38, that is, the thread rubbers 33, 33 of the belt portion 32, and the thread rubbers 38, 38 of the leg flange portions 37 are fixed in a state of being elongated in the longitudinal direction. Further, in this example, as shown in FIG. 2B, the portion of the belt portion 32 that becomes the waist opening portion BH is provided with a terminal end structure for the skin pressure reduction. In the diaper 1 in the extended flat state, the lateral inner end portions 32eW1 and 32eW1 of the belt portion 32 are portions that become the waist opening portion BH, but the end portions 32eW1 and 32eW1 are folded back in the lateral direction. The folding state is fixed by an adhesive or the like, whereby the load on the wearer's skin is reduced. In addition, the thickness of the end portion (the end portion on the side of the waist opening portion BH) closer to the lateral direction than the lateral center portion of the belt portion 32 is thickened by the end end tail structure as described above. Thereby, the cushioning property in the waist opening portion BH is increased, and when the diaper 1 is worn, the upper end portion (end end structure) of the belt portion 32 is disposed at a position higher than the apex of the wearer's pelvis (tibia). Near the upper side, the portion having the thickness is caught at the outward projection of the pelvis, whereby the belt portion 32 is less likely to slip down to the lower side. Therefore, the fit of the diaper 1 can be improved. However, it is not limited to this. That is, the end portion end structure may be omitted without folding back the end portion 32eW1. As shown in FIG. 3A, each of the end portions 10eLf and 10eLb in the longitudinal direction of the absorbent body 10 is tapered to form a sheet-like member having a substantially V-shaped shape in plan view. In other words, each of the end portions 10eLf and 10eLb of the absorbent main body 10 in the longitudinal direction has a shape corresponding to the pair of front side joint portions jf and jf and the pair of rear side joint portions jb and jb. Further, as shown in FIG. 3B, the same absorbent body 10 has an absorbent body 11 that absorbs excretion liquid such as urine, and a top surface sheet 12 that is disposed on the skin side closer to the skin side than the absorbent body 11; The absorbent body 11 is closer to the liquid-impermeable back sheet 14 on the non-skin side, and the outer sheet 16 is disposed closer to the non-skin side than the back sheet 14. [0054] Next, each of the members 11, 12, 14, and 16 is joined to a member adjacent in the thickness direction by a hot melt adhesive, welding, or the like. In other words, in the respective end portions 10eLf and 10eLb in the longitudinal direction of the absorbent body 10, the members 11, 12, 14, and 16 are joined in a laminated state, and are fixed in the longitudinal direction. Thereby, each of the end portions 10eLf and 10eLb is less likely to extend in the longitudinal direction (longitudinal direction in the shape of the pants), and the absorbent body 10 is easily accommodated in the undergarment. The influence of the extension of each of the end portions 10eLf and 10eLb will be described later. In addition, the coating pattern of the adhesive agent which joins each member can be exemplified by an Ω pattern, a spiral pattern, a stripe pattern, etc., and it is not only about the other adhesive agent which arises later, but also about the above-mentioned adhesive agent. Further, when the diaper 1 is worn under the undergarment, since the diaper 1 is hidden in the underpants, the dimension of the longitudinal direction of the absorbent body 10, that is, the length of the article is preferably as short as possible. Specifically, it is preferably 450 to 750 mm. In other words, if it is less than 450mm, it will not cover the buttocks, which will help to feel uncomfortable. If it exceeds 750mm, it will exceed the waistline, and it will cause a sense of discomfort when worn. However, if it is formed into the above range, it can prevent such situations, and the diaper 1 is not easy to get from the underwear. protruding. [0056] The absorbent body 10 of the present embodiment has an arc on the outer side in the longitudinal direction (the upper side in the longitudinal direction of the pants shape) in the center of the lateral direction and the end portion on the side in the longitudinal direction. A protruding front end projection 10s. When the diaper 1 is formed into a pants shape, the front end protruding portion 10s protrudes upward from the upper end (end portion 32eW1) of the belt portion 32 in the center in the lateral direction (refer to FIG. 1 and the like), whereby the user easily The lateral center position of the diaper 1 (absorbent body 10) is recognized. Thereby, when the diaper 1 is worn, the absorbent body 10 can be easily attached to the correct position of the body, and the occurrence of leakage of the excrement due to the wearing of the absorbent body 10 in the laterally displaced state can be suppressed. . [0057] When the operation of wearing the diaper 1 is started, it is confirmed whether or not the diaper 1 is accommodated in the undergarment in the front side and the back side, so that the front end protruding portion 10s is provided on the back side of the absorbent body 10. Both ends of the ventral side are preferred (see Figs. 2, 3, etc.). Therefore, when the diaper 1 is worn, it is easy to visually recognize the back side and the ventral side, and the center part of the diaper 1 does not protrude from the underwear, and can be easily adjusted so that the whole diaper 1 does not protrude from the underwear. The absorber 11 has a liquid absorbing absorbent core (not shown) and a core sheet (not shown) that covers the outer peripheral surface of the core. The absorbent core is formed into a predetermined shape by forming a predetermined liquid absorbing material. In the example of FIG. 3A, it is a substantially rectangular molded body in a plan view in which the front end and the rear end have arc-shaped portions. However, it is not limited to this. In addition, the liquid-absorbent material such as a liquid absorbent fiber such as pulp fibers or a highly absorbent polymer (so-called SAP) may be exemplified, but is not limited thereto. Further, in the core sheet, a liquid permeable sheet such as a face paper or a non-woven fabric may be used, but the core sheet may be omitted as appropriate. Among them, the dimension in the longitudinal direction of the absorbent body 11 is preferably from 35 to 85% of the length of the above-mentioned product. The reason is based on the fact that if the absorbent body 11 cannot cover the inter-turn portion and leaks if it is not more than 35%, on the other hand, if it exceeds 85%, it may cause a feeling of discomfort during wearing. [0059] The width W11 in the state in which the absorber 11 is elongated in the lateral direction (that is, the distance between the end of the one side of the absorber 11 in the lateral direction and the end of the other side) is 50 mm or more and 120 mm or less. It is suitable (120mm ≧ W11 ≧ 50mm). By forming the width W11 of the absorbent body 11 to 120 mm or less, when the diaper 1 is worn under the undergarment, it is easy to accommodate the absorbent body 11 in the crotch portion without delay in the crotch portion. In addition, by forming the width W11 to 50 mm or more, it is easy to sufficiently ensure the area (absorption capacity) for absorbing excrement or the like. Further, a plurality of groove portions 17 are formed on the surface of the absorber 11. In the present embodiment, the groove portion 17 includes a first groove portion 171, a second groove portion 172, and a third groove portion 173 (see FIG. 2). The groove portion 17 is formed in a linear shape along the longitudinal direction in the center of the lateral direction of the absorber 11. The second groove portion 172 passes through the center in the lateral direction of the first groove portion 171 and faces the rear side in the longitudinal direction while intersecting with a straight line along the longitudinal direction (that is, a straight line corresponding to the extension line of the first groove portion 171). The back side is expanded toward the outer side of the lateral direction to form a parabolic shape. The third groove portion 173 is formed in a parabolic shape that extends toward the front side (ventral side) in the longitudinal direction and extends outward in the lateral direction while intersecting the first groove portion 171, on the front side in the longitudinal direction of the second groove portion 172. [0061] The groove portions 17 each press the press portion formed on the surface of the absorber 11 by a predetermined pressing means. However, the groove portion 17 is not formed as a press portion of the press absorbing body 11, and may be formed as a slit. In addition, it may be formed by arranging a plurality of press portions of a dot shape or other shapes instead of being formed in a line shape as shown in FIG. The first groove portion 171 has a function as a bending inducing portion that induces the absorber 11 to be bent in the thickness direction. Specifically, when the diaper 1 is worn, the absorbent body 11 is bent along the first groove portion 171 to form a mountain shape that protrudes toward the wearer's skin side along the first groove portion 171, thereby being able to be worn. The body shape of the person causes the absorbent body 11 to be appropriately deformed. Among them, the diaper 1 of the present embodiment is imaginarily worn under the undergarment, and the absorbent body 11 is disposed at a position closer to the wearer's body than the undergarment. Since the inter-turn width (the width of the crotch portion) of the general pants is in the range of 50 to 80 mm, the absorbent body 11 is deformed by providing the first groove portion 171, whereby the crotch portion can be widened within the crotch portion width of the underpants. The absorbent body 11 is reliably housed. That is, by forming the above-described size range (120 mm ≧ W11 ≧ 50 mm), the absorbent body 11 is three-dimensionally deformed along the concave-convex shape of the body, and the lateral width of the absorbent body 11 can be narrowed. Thereby, in the crotch portion, the absorbent body 11 is less likely to protrude more from the undergarment. Further, in a region closer to the back side than the region in which the first groove portion 171 is disposed, the force for deforming the absorber 11 into a mountain shape is transmitted to the outside of the lateral direction by the second groove portion 172, and the absorber The 11 is easily held in a planar shape in the back side region, so that it is easy to fit on the flat portion of the wearer's back. Further, since the absorber 11 is easily deformed into a curved shape along the parabola of the third groove portion 173, good adhesion to the arc of the wearer's buttocks can be achieved. [0064] The top sheet 12 is formed of a liquid permeable sheet such as a nonwoven fabric, and an air flow non-woven fabric is used here. That is, the top sheet 12 corresponds to "skin side non-woven fabric". The planar size of the top sheet 12 is as shown in FIG. 3A, and is a size as protruded from both sides in the longitudinal direction of the absorbent body 11 and both sides in the lateral direction. Then, the laterally projecting portions 12eW and 12eW are bent toward the non-skin side and the laterally inner side as shown in Fig. 3B, whereby the protruding portions 12eW, 12eW also cover the lateral end portions of the absorbent body 11 by the non-skin side. 11eW. Therefore, the lateral end portions 12eW, 12eW of the top sheet 12 do not rub against the skin, so the feeling of discomfort during wearing is reduced. [0065] The back sheet 14 is formed of a liquid-impermeable sheet such as a polyethylene film or a polypropylene film. That is, the back sheet 14 corresponds to the "non-skin side film". The back sheet 14 is also a sheet member having a planar size as protruded from both sides in the longitudinal direction of the absorbent body 11 and both sides in the lateral direction. [0066] The exterior sheet 16 is formed of a soft sheet such as a nonwoven fabric. That is, the exterior sheet 16 corresponds to "outerwear nonwoven fabric". The exterior sheet 16 is a sheet member having a size that protrudes from both sides in the longitudinal direction of the back sheet 14 and both sides in the lateral direction. [0067] Incidentally, in the following description, there is a case where the expression "the skin side surface of the absorbent body 10" is used, but the sheet forming the skin side surface of the absorbent body 10 depends on the plane position of the body 10. change. That is, at the position where the top sheet 12 is present, the skin side surface of the top sheet 12 forms the skin side surface of the absorbent body 10. However, in the position where the back sheet 14 is present without the top sheet 12, the skin side surface of the back sheet 14 forms the skin side surface of the absorbent body 10, and the top sheet 12 and the back sheet 14 do not exist. At the position, the skin side surface of the exterior sheet 16 forms the skin side surface of the absorbent body 10. [0068] Each of the end portions 10eLf and 10eLb in the longitudinal direction of the absorbent body 10 is provided with a hydrophobic sheet 50, 50 so as to cover the side surface of the skin of the absorbent body 10 (refer to FIG. 3, reference is made to FIG. The part of the point pattern). That is, a hydrophobic sheet 50 is laminated on the skin side of the top sheet 12 (skin side non-woven fabric). Each of the end portions 10eLf and 10eLb in the longitudinal direction of the absorbent body 10 is a portion that can face the wearer's abdomen or buttocks when the diaper 1 is worn, and the skin side of each of the end portions 10eLf and 10eLb When the excretion fluid gets wet, there is a feeling of discomfort to the wearer. On the other hand, the hydrophobic sheet 50 is provided on the skin side surface of each of the end portions 10eLf and 10eLb, whereby the excretion liquid absorbed by the absorbent main body 10 is prevented from returning to the skin side and oozing out, so that it is not easy for the wearer to bring it. Comfortable. [0069] wherein, the top sheet 12, the back sheet 14, the exterior sheet 16, and the hydrophobic sheet 50 are both shown in the longitudinal direction (longitudinal direction) closer to the upper end 11eLf than the absorber 11 as shown in FIG. (waist side) protruding part. Further, the top sheet 12, the exterior sheet 16, and the hydrophobic sheet 50 have portions that protrude above the upper end (waist side) of the upper end 14eLf of the back sheet 14. In the diaper 1 of the present embodiment, the top surface sheet 12 is included in the upper portion 10uf of the absorbent body 10 which is closer to the upper side than the upper end 14eLf of the back sheet 14 (non-skin side film). At least three layers of the outer sheet 16 and the hydrophobic sheet 50. In FIG. 4, the cross-sectional structure of the absorbent body 10 is shown only for the abdominal side in the longitudinal direction, but the absorbent body 10 also has substantially the same cross-sectional structure for the back side. In other words, the absorbent main body 10 has at least three layers in a region 10ub (none of which is shown) which is closer to the upper side than the upper end 14eLb on the back side of the back sheet 14 (non-skin side film). [0070] Next, at the end portions 10eLf, 10eLb in the longitudinal direction of the absorbent body, the respective layers (sheet members) are joined to each other in a laminated state. In the case of a general pants-type diaper, the laminated sheet members are joined to each other by an elastic member (wire rubber) interposed therebetween. That is, the sheet members having the laminated layers are bonded to each other at a portion where the elastic members are present, but the portions where the elastic members are not joined are not joined to each other, and the portions where the sheets are not joined when the sheet members are stretched are easily stretched. On the other hand, in the present embodiment, since the laminated sheet members are joined to each other in a plane, the entire structure has a structure that is not easily stretched. [0071] === Regarding the wearing form of the diaper 1 === As described above, the diaper 1 of the present embodiment can be worn under the undergarment. In particular, when an adult wears underpants from above the diaper 1, it is not easy to produce a feeling of discomfort when wearing the diaper, and the wearer can wear the general underwear and feel the daily life. If the diaper 1 is worn together with the underpants, the diaper 1 is placed on the inner side (skin side) of the undergarment in advance, and after the leg opening portion passes through the wearer's foot, the diaper 1 is pulled up together with the underwear, thereby being effortlessly Wear diapers 1 and underwear. Of course, it is also possible to wear the underpants from above after wearing the diaper 1. [0072] FIG. 5 is a schematic view showing a state in which the wearer wearing diaper 1 is viewed from the front side (ventral side) and the underpants are put on the pants. In the same Fig. 5, the underpants are indicated by solid lines, and the diaper 1 is indicated by broken lines. Fig. 6 is a schematic plan view showing a diaper 1 of a pants-type shape viewed from the front side (ventral side) in a natural state. "Natural state" refers to a state in which the diaper 1 is placed for a predetermined period of time. For example, the belt portion 32 of the diaper 1 is stretched toward both outer sides in the lateral direction, and the belt portion 32 and the absorbent main body 10 are formed in an "extended state", and the stretched state is continued for 15 seconds, and then the stretching of the diaper 1 is released. And placed on a flat surface such as a table. Next, the state after the lapse of 5 minutes in the plane flat state shown above is a natural state. Fig. 7 is a schematic plan view showing a state in which the pants-type diaper 1 is elongated in the longitudinal direction and the lateral direction. Here, the "state in which it is stretched" in Fig. 7 is synonymous with the "extended state" described above. Further, in the natural state, the belt portion 32 is inclined obliquely with respect to the lateral direction as shown in Fig. 6, but in an elongated state, it is formed into a shape elongated in the lateral direction as shown in Fig. 7 . When the diaper 1 is worn over the underwear, as shown by the thick dotted arrow in FIG. 5, the lateral side portions of the belt portion 32 of the diaper 1 and the side portions of the undergarment are grasped in an oblique direction. Stretching action. In the diaper 1, the pair of belt portions 32 and 32 disposed on the lateral sides are respectively obliquely joined to the absorbent body 10 by the front side joint portions jf and jf (the rear side joint portions jb and jb), and thus are in a natural state. Next, the longitudinal direction of the belt portion 32 faces the obliquely upward direction. Specifically, as shown in FIG. 6, when the laterally outer end and the longitudinally upper end of the belt portion 32 are the upper end 32eou, the position of the upper end 32eou is higher than the upper end of the absorbent body 10 in the natural state. The position of the upper end of the projection 10s is closer to the upper side of the longitudinal direction. Further, when the laterally outer end and the longitudinal lower end of the belt portion 32 are the lower end 32eod, the position of the lower end 32eod is closer to the lateral direction than the position of the upper end 32eou in the natural state. With this configuration, the belt portion 32 in the natural state is inclined toward the outer side in the lateral direction and the upper side in the longitudinal direction with respect to the absorbent body 10. Next, the belt portion 32 is provided with the thread rubber 33 along the longitudinal direction. Therefore, the thread rubber 33 is elongated in the longitudinal direction by the force of stretching the belt portion 32 in the obliquely upward direction, and the belt portion 32 is extended. Show flexibility. By the stretchability, the absorbent body 10 is efficiently stretched upward in the oblique direction from both sides in the lateral direction by the belt portion 32 and the front joint portion jf, and the absorbent body 10 is easily fitted while being expanded in the width direction. In the wearer's crotch. [0075] In a general diaper, the elastic member is disposed so as to be laterally stretched and contracted. Therefore, if the force is to be applied in an oblique direction, it is necessary to perform the action of stretching in the lateral direction and then pulling in the longitudinal direction, and any part of the belt member is easy. Deformation occurs. On the other hand, in the configuration of the diaper 1, in the natural state, the belt portion 32 faces obliquely upward, so that when the grip belt portion 32 is pulled up, the force is easily applied obliquely, and when the belt portion is pulled upward, the force is not Focusing locally, the force is easily transmitted to the entire area of the absorbent body 10 located on the extension line of the belt portion 32. That is, the absorbent body 10 which is not easily stretched by the stretching force by the thread rubber 33 is easily pulled up. Further, the portion grasped by the hand when the diaper 1 is worn, that is, the lateral end portions of the belt portion 32 is also formed obliquely (based on the positional relationship between the upper end 32eou and the lower end 32eod), so that the belt portion 32 can be easily pulled up. [0076] wherein the general underpants are formed of materials that are easily stretchable in the longitudinal direction and the transverse direction (for example, polyurethane elastic fibers, etc.), so that if the belt portion of the diaper does not have sufficient stretchability, when the diaper and the underpants are overlapped, The expansion and contraction of the belt portion cannot follow the expansion and contraction of the undergarment, and it is difficult to wear both. Further, in general, the disposable diaper is in a natural state, the belt portion is not oriented obliquely, and the joint portion where the absorbent body and the belt portion are joined is not oriented in the oblique direction. Therefore, although the force for stretching the belt portion is easily transmitted to the lateral direction, it is not easily transmitted to the longitudinal direction, and it is not easy to interlock with the force of the underwear. On the other hand, in the diaper 1 of the present embodiment, the joint portions jf and jb are formed obliquely, and the belt portion 32 is oriented obliquely in the natural state, and the lateral end portion of the belt portion 32 is also oriented obliquely. The force is easily applied in an oblique direction. Thereby, the force of the upward pulling up which occurs when the panties which are stretchable in the longitudinal direction or the lateral direction are easily extended is interlocked with the belt portion 32, and as a result, the diaper 1 can be worn without being detached from the underpants. Further, the minimum value of the width in the longitudinal direction of the belt portion 32 is set to h32 (refer to FIG. 7). That is, the minimum value of the distance between the end of one side of the belt portion 32 and the end of the other side in the h32 longitudinal direction. In the diaper 1, it is prescribed that the distance h32 is 50 mm or more and 100 mm or less (100 mm ≧ h 32 ≧ 50 mm). By setting h32 to 100 mm or less, when the diaper 1 and the underpants are overlapped, the belt portion 32 is less likely to protrude from the side portion of the undergarment. On the other hand, when h32 is 50 mm or more, the contact area between the wearer's skin and the belt portion 32 can be sufficiently ensured, and the friction between the belt portion 32 and the wearer's skin can easily suppress the belt portion 32 from slipping. Or a situation in which the circle becomes thinner and thinner. In addition, when the adult grasps the object, the length of the index finger and the thumb is extended to about 100 mm. Therefore, if the size is as shown above, the adult can easily grasp the belt portion 32 with one hand, and the belt portion 32 can be stably inclined upward. The action of stretching in the direction. By these, the fit of the belt portion 32 can be improved, and it is difficult to protrude from under the undergarment. [0079] After the belt portion 32 is stretched upward obliquely upward, as shown by the thick solid arrow in FIG. 5, the ventral end portion 10eLf of the absorbent body 10 and the back side end portion 10eLb (in FIG. 5) The operation is performed by pulling up the upper side and pulling the absorber 11 to the crotch portion. In the pull-up operation, the upper end (edge) of the end portion 10eLf (10eLb) of the absorbent body 10 is often caught and stretched. However, if the diaper is formed of soft material such as non-woven fabric, it is pulled. The stretched part is stretched. In particular, since the diaper 1 of the present embodiment is imaginarily overlapped and worn under the undergarment, if the end portion 10eLf (10eLb) is stretched, the stretched portion protrudes from the undergarment. Further, since the nonwoven fabric is stretched, the absorbent body 11 cannot be pulled up firmly, and the fit is deteriorated. On the other hand, in the diaper 1, in the end portion 10eLf (10eLb) in the longitudinal direction of the absorbent body 10, a predetermined number of sheet members are laminated to increase the strength, whereby the region is not easily stretched. Specifically, as shown in FIG. 4, the absorbent body 10 is configured in the end portion 10eLf so as to have a laminated structure of at least three or more layers. For example, in the vertical direction, in the region 10uf which is closer to the upper side than the upper end 14eLf of the back sheet 14 (non-skin side film), there are a top sheet 12 (skin side non-woven fabric), an exterior sheet 16 (outerwear non-woven fabric), and The hydrophobic sheet 50 is formed into three layers. Further, in the longitudinal direction, in the region 10mf between the upper end 14eLf of the back sheet 14 and the upper end 11eLf of the absorbent body 11, in addition to the above three layers, there are four layers including the back sheet 14 (non-skin side film), and thus the strength More improved. Further, in addition to this, other non-woven fabrics or the like may be laminated. [0081] FIG. 8 is a graph showing the results of tests conducted on tensile strength of a diaper. In the same manner as in FIG. 8, the diaper 1 of the present embodiment and the diapers (known products) of the two types of products formed by the nonwoven fabric are used as the sample 1 and the sample 2, and the longitudinal direction of the absorbent main body 10 is shown. The relationship between the load and the extension when the end region (corresponding to the region of the region 10uf) is stretched toward the upper side in the longitudinal direction. [0082] Each of the sample 1 and the sample 2 has a belt member which is continuous in the lateral direction, and the number of layers of the sheet member in the region corresponding to the end portion 10eLf (the region 10uf in the diaper 1) is 2 or less. Disposable diapers. More specifically, the sample 1 is disposed in the lateral direction in an elastic member (filament rubber) exhibiting stretchability in the lateral direction, and the elastic member has a discontinuous portion in a central portion (a portion corresponding to the region 10uf) in the lateral direction. Next, in the discontinuous portion, the two non-woven fabrics which are laminated with the elastic member interposed therebetween are formed to be non-joined. On the other hand, in the sample 2, the elastic members (filament rubber) exhibiting stretchability in the lateral direction are continuously arranged in the lateral direction, and the two nonwoven fabrics disposed between the elastic members are transmitted through the elastic members in the lateral center portion (equivalent Engaged in the portion of the region 10uf). The sample 1, the sample 2, and the diaper 1 shown above were stretched by a tensile tester in a region corresponding to the region 10uf, and the amount of stretching when the load was increased was measured. That is, in the sample 1, a tensile test was performed on a portion where the two sheet members were not joined, and in the sample 2, a tensile test was performed on a portion where the two sheet members were intermittently joined, in the diaper 1, A tensile test was performed on a portion where three sheet members were joined in the longitudinal direction (longitudinal direction). As a result, the load was increased and the amount of stretching was increased in either of them. In Sample 1, the amount of stretching at a load of 50 N was about 7 mm, and the load at the time of stretching was about 70 N, making it difficult to perform accurate measurement thereafter. Next, in the sample 2, the amount of stretching at a load of 50 N was about 16 mm, and the load at the time of stretching was about 100 N, and it was difficult to perform accurate measurement thereafter. On the other hand, in the diaper 1 of the present embodiment, the amount of stretch at a load of 50 N is 1 mm or less, the amount of stretch at a load of 100 N is about 2 mm, and then the load at the limit of stretch is about 300 N. As described above, it is clear that in the diaper 1, in the end portion 10eLf (10eLb) of the absorbent body 10, the end portion 10eLf (10eLb) is provided by a laminated structure in which at least three or more sheet members are joined, respectively. The strength is extremely high compared to conventional products, and it has a structure that is difficult to stretch for stretching. Therefore, even when the diaper 1 is worn, in the case where the region 10uf is stretched toward the upper side, the region is prevented from being stretched, the absorbent body 10 is less likely to protrude from the undergarment, and the absorbent body 11 is firmly pulled up, thereby achieving Good fit. Further, in the diaper 1, the length L10uf of the region 10uf in the longitudinal direction is 20 mm or more. In the longitudinal direction, the upper end 14eLf of the back sheet 14 (non-skin side film) is closer to the upper side than the upper surface 14eLf of the back sheet 14, and the length of the layer of the sheet member layer of 3 or more layers is 20 mm or more (L10uf ≧ 20 mm). . As shown by the hatched portion in Fig. 7, the region 10uf is attached to the upper end of the absorbent body 10 and sandwiched between the pair of front side joint portions jf, jf, and when the diaper 1 is worn, when the wearer stretches the absorbent In the case of the body 10, it is easy to grasp the area with a finger. Therefore, by forming the region into a three-layer structure, the wearer can easily perform the operation of pulling up the absorbent body 10 by forming a region of a size that is easy to grasp while ensuring sufficient strength. In the upper end of the longitudinal direction of the absorbent body 10, the front end projecting portion 10s is provided. However, in the present embodiment, the length of the portion other than the front end projecting portion 10s of the region 10uf is 20 mm or more (refer to FIG. 7). . Further, in the longitudinal direction, the length L10s of the distal end protruding portion 10s which protrudes closer to the upper side than the upper end of the front side joint portion jf (the rear side joint portion jb) (that is, the upper end position of the belt portion 32) is 1 mm or more and 5 mm or less ( 5mm≧L10s≧1mm). If L10 is shorter than 1 mm, the front end protruding portion 10s itself becomes difficult to recognize, and it is difficult to recognize the lateral center position of the diaper 1. In addition, when L10 is longer than 5 mm, the front end protruding portion 10s is curled or bent, and the function as a symbol indicating the center position in the lateral direction cannot be exhibited. Further, if L10 becomes long, the front end projection 10s protrudes from the underpants. On the other hand, by forming 5 mm ≧ L10 s ≧ 1 mm, there is no case where it protrudes from the underpants, and the center position in the lateral direction can be easily recognized. Further, the length L10uf in the longitudinal direction of the region 10uf in the absorbent body 10 is more than the length L32eW1 in the longitudinal direction of the portion (the end end tail configuration described above) in which the upper end portion 32eW1 of the belt portion 32 is folded back. long. Thereby, the force which the region 10uf of the absorbent body 10 is pulled upward is easily transmitted to the upper end portion 32eW1 of the belt portion 32 through the front joint portions jf and jf. That is, the entire region in the longitudinal direction of the upper end portion 32eW1 of the band portion 32 is easily pulled up to the upper side together with the region 10uf of the absorbent body 10. Therefore, by performing the operation of pulling up the upper end portion 10eLf of the absorbent body 10, the position (height) of the entire waist opening portion BH including the belt portion 32 can be adjusted. Thereby, the fit of the diaper 1 is improved, and the waist opening portion BH of the diaper 1 is less likely to protrude from the undergarment. Further, when the diaper 1 is viewed from the lateral direction, the region 10uf at the upper end in the ventral side of the absorbent body 10 and the region 10ub at the upper end in the absorbent body 10 respectively form pleats protruding in the thickness direction. In the waist opening portion BH, the belt portion 32 acts on the longitudinal direction of the belt portion 32 by the thread rubber 33. On the other hand, the regions 10uf and 10ub at the upper end of the absorbent body 10 do not function. Scalability. In other words, the belt portion 32 having the stretchability is disposed on both lateral sides of the regions 10uf and 10ub, and the joint portions jf and jf are obliquely stretched from both sides, whereby the planar shape of the end portions 10uf and 10ub is easily deformed. Due to this deformation, wrinkles are easily formed. The size of the wrinkles varies depending on the inclination angle of the joint portions jf, jb or the lengths L10uf, L10ub in the longitudinal direction of the regions 10uf, 10ub, but in the present embodiment, the end portion on the ventral side of the absorbent body 10 is formed. The maximum value of the height in the thickness direction of the wrinkles of 10eLf is smaller than the maximum value of the height in the thickness direction of the wrinkles formed at the end portion 10eLf of the ventral side. Thereby, when the diaper 1 is overlapped and worn under the undergarment, the diaper side is suppressed by the influence of the wrinkles, the non-skin side of the underwear in the thickness direction is excessively lifted, or the diaper 1 is confused under the underpants. In the case, it is easy to obtain good fit. Further, the wrinkles are narrowed on the ventral side, whereby the diaper 1 is less likely to be noticeable under the underpants. The embodiment of the present invention is described above, but the above-described embodiments are intended to facilitate the understanding of the present invention and are not intended to limit the present invention. In addition, the present invention may be modified or modified without departing from the gist thereof, and the equivalents thereof are included in the present invention. For example, a deformation as shown below can be performed. In the above-described embodiment, the so-called three-dimensional folded edges for preventing lateral leakage are not provided at positions on both sides in the lateral direction of the absorbent body 10 in the unfolded state of FIG. 3A, but may be provided as appropriate. However, it is preferable that the three-dimensional hemming is not provided as in the above embodiment. The details are as follows. First, in order to provide a three-dimensional hemming, a pair of three-dimensional hemming sheets which are fixed in a state in which the elastic members such as the thread rubber in the longitudinal direction are elongated in the same direction are respectively fixed to the lateral direction of the absorbent body 10. On both sides. Further, in the portion of the same three-dimensional hemming sheet which is closer to the lateral direction than the portion fixed to the absorbent body 10, both end portions in the longitudinal direction are also fixed to the absorbent body 10. Then, the portion on the inner side is not fixed to the central portion in the longitudinal direction of the absorbent body 10, and is erected according to the contraction force of the elastic member, whereby the central portion functions as a three-dimensional hemming. However, since the both end portions to be fixed are convex on the skin side, they are likely to rub against the buttocks of the wearer and the like, and as a result, the wearing feeling is lost. In addition, it is easy to think of a diaper in appearance. Therefore, it is preferable that the three-dimensional folded edges are not provided. In the above-described embodiment, the cross-sectional shape of the front side joint portion jf and its proximal portion is not described. Therefore, it will be described here with reference to FIGS. 9A and 9B. Figure 9A is a cross-sectional view taken along line D-D of Figure 7. Figure 9B is a cross-sectional view taken along line E-E of Figure 7. In other words, Fig. 9A shows a cross section of both longitudinal end portions (near the waist opening portion BH and the leg circumference opening portion LH) of the front side joint portion jf, and Fig. 9B shows a vicinity of the longitudinal middle portion of the front side joint portion jf. section. As shown in FIG. 9A and FIG. 9B, the front side joint portion jf is formed to protrude upward from the front side (non-skin side) in the front-rear direction. Then, since the hydrophobic sheet 50 is present on the non-skin side of the absorbent body 10 of the front side joint portion jf, the angle θ1 at the boundary portion between the absorbent body 10 and the front side joint portion jf becomes an obtuse angle according to the rigidity of the sheet 50. The angle θ2 of the boundary portion between the belt portion 32 and the front side joint portion jf is an acute angle, and the front joint portion jf is in a state of being reversed outward in the lateral direction. Further, a dry edge jde in which the belt portion 32 and the absorbent body 10 are not joined is provided on the outer edge portion of the front side joint portion jf. Then, the width of the dry edge jde (that is, the length of the portion which is closer to the non-skin side than the portion where the belt portion 32 is joined to the absorbent body 10) is the shortest at both ends in the longitudinal direction, and is the center in the longitudinal direction. The ministry is the longest. In the manufacturing process of the diaper 1, the dry edge jde is separated by the edge of the front side joint portion jf when the absorbent body 10 and the belt portion 32 which are overlapped in the thickness direction are cut along the front side joint portion jf. The position of the distance is cut off. At this time, in order to prevent the front side joint portion jf itself from being cut, the dry side jde is generally formed as large as possible by cutting the edge of the front side joint portion jf to a certain extent. However, the diaper 1 of the present embodiment is imaginarily overlapped and worn under the undergarment, so that the side jde is too large and it is easy to interfere with the underpants. In particular, in the vicinity of the waist opening portion BH or the leg opening portion LH, a plurality of sides jde are formed to be large, and the undergarment is fastened during wearing, which may cause a feeling of discomfort in the waist circumference or the leg circumference. Therefore, in the diaper 1, the width of the dry side jde in the both end portions in the longitudinal direction of the front side joint portion jf is shorter than the width of the dry side jde in the center portion in the longitudinal direction of the front side joint portion jf. The way to form the dry side jde. Therefore, when the diaper 1 is worn, it is possible to prevent the wearer from feeling a sense of discomfort in the waist circumference or the leg circumference. Among them, the same applies to the rear side joint portion jb.
